Feeling the Heat

August 5, 2024

“Meltdown” is the buzzword used when computer glitches throw air travel into disarray, as happened a couple of weeks ago. But is there a more literal application? How do extreme temperatures impact air travel? The question is important, as heat waves pummel the globe and we keep breaking records for the hottest-ever temperatures.

On the most basic level, hot weather affects air travel the way it affects most things: it makes people uncomfortable and wears them down. Things happen more slowly. With all that nonreflective asphalt and open space, airports become “heat islands,” subjecting people and equipment to sometimes unbearable conditions. Imagine what it’s like slinging suitcases out on the tarmac when the mercury hits triple digits.

Workers are subject to overheating, and so is their equipment: tugs, tractors, cart and lifts — all the myriad moving parts of airport logistics. Airplanes themselves, meanwhile, have a lot of internal machinery, both electronic and mechanical, and much of it runs hot to begin with. Throw in soaring temps and things can break down.

Aerodynamically, warmer air is less dense than cooler air, meaning that in hot weather a wing produces less lift. Jet engines don’t like this low-density air either, producing less thrust. Engines also are subject to internal temperature limits — exhaust gas temps, etc. — beyond which operation isn’t permitted. Together, this dictates higher takeoff and landing speeds — which, in turn, increases the amount of required runway.

What all of that means for travelers is that your flight might be weight-restricted and unable to take a full load of people or cargo. How much so will vary with the temperature and runway length.

Outright grounding of flights is rare, but at a certain point that can happen too. Some aircraft have a hard temperature limit — usually around 50 degrees Celsius — beyond which taking off simply isn’t permitted. We also get a detailed paper printout before each departure that factors in weight, temperature, wind, runway length, and so forth, providing us with the speeds, thrust, and flap settings that we’ll use for takeoff. Sometimes, above certain temperatures, data doesn’t exist.

So, you could say there are hard and soft limits. The aerodynamic limits are soft. That is, you don’t know for sure if a flight can safely depart, or at what weight, until you juggle the numbers. The hard limits are the absolute temperature maximums, set by the manufacturer, that you’re not allowed to exceed.

If your flight is weight-restricted — or canceled — you’re liable to get a dumbed-down synopsis over the gateside loudspeaker or from your pilots. Something along the lines of, “We’re sorry but it’s too hot to fly today.” This makes it sound subjective, or up to the whims of the crew, but in reality it’s more scientific.

Extreme heat is no fun for airlines or their customers. Unfortunately, you can expect more of it as climate change causes more and more extreme weather events, including extreme heat waves.

It’ll be especially interesting to see the effects on those carriers whose hubs are located in what are already the hottest places on earth. The Gulf Carriers, for example (Qatar, Emirates, and Etihad) or Saudia, or Air India. Fortunately for them, many of their long-haul flights arrive and depart in the dead of night, when it’s cooler.

All well and good, but I’ve failed to address the one question you’re lining up to ask: Why are are planes so damn hot when parked at the gate?

Well, a plane’s air conditioning is supplied one of three ways:

1. Via the engines. Air for the “packs” as the AC units are called (it’s an acronym from the words “pneumatic air cycle kit”), is plumbed from the engine compressors. This is the most effective way of cooling or heating the cabin.

2. However, planes can’t run their engines at the gate. And so, during boarding and deplaning, air is supplied to the packs via the plane’s APU, or auxiliary power unit. This is a small jet engine usually located up under the tail. The APU can power the packs as necessary, but they won’t run as robustly as when the main engines are supplying the air.

3. Via an external air supply. You’ll sometimes see fat, caterpillar-like hoses connected to the belly of a plane. These provide hot or cold air as requested from an air conditioning unit attached to the jet bridge. The effectiveness of this method tends to vary plane to plane and gate to gate.

Variations in 2. and 3., above, are the reason the cabin is sometimes sweltering. Or, in winter, freezing cold.

Things Going Bump

July 15, 2024

Everyone’s talking about turbulence. Each week now, it seems, we’re reading about this or that flight getting wracked around by unusually rough air. People are being injured, flights are diverting. In one case a passenger died after a Singapore Airlines flight hit severe turbulence over Southeast Asia.

Are dangerous turbulence encounters becoming more prevalent, or are they merely getting more attention?

I honestly don’t know. That’s a bummer of an answer, but I’m unaware of any stats indicating things one way or the other. For now it’s all pretty anecdotal.

That includes my own observations. For instance I seem to notice more and larger thunderstorms these days — over the U.S., over the Atlantic — than I did in years past, but that’s without any objective measuring; it’s just a hunch.

Either way, the media loves a scary-sounding airplane story. In an age when large-scale air disasters have become vanishingly rare, news sources — to say nothing of social media — have taken to hyping minor mishaps instead. That Singapore Airlines incident (the passenger actually died from a heart attack after the turbulence upset) got as much coverage as a crash that killed 200 people would have gotten in decades past.

Another factor is the number of planes in the air. There are more than twice as many commercial flights aloft at any given moment as there were a generation ago. More flights, more people; an uptick in incidents is inevitable.

It’s also possible that yes, turbulence is getting worse. It stands to reason that as climate change intensifies weather patterns and causes bigger, more powerful storms, flying will, to a small but perhaps measurable extent, be bumpier.

How much bumpier is impossible to know, but cases where passengers are hurt or aircraft are damaged will likely remain uncommon. (This is being studied as we speak, though you can expect any results pointing to climate change to set off further squabbling rather than, as it were, clearing the air.)

Also helping are the technological tools now at our disposal. The weather apps that we use in the cockpit are far more advanced than they were even five years ago, and are remarkably accurate when it comes to predicting the where, when, and how bad of turbulence — and how best to avoid it.

Even in worst-case turbulence encounters, meanwhile, the seat belt will probably keep you safe. The vast majority of turbulence-related injuries are suffered by crew members moving through the cabin, or passengers who weren’t belted in when they should’ve been. Flights might get bumpier, but the basics of staying unhurt remain the same.

Wrong Way Woes

April 23, 2019

DID YOU HEAR the one about the flight that went to Edinburgh instead of Dusseldorf?

On March 25th, a British Airways regional jet took off from London City Airport (LCY) bound for Dusseldorf, Germany. An hour or so later, the passengers found themselves in Edinburgh, Scotland. Not until the jet touched down did they realize they were headed to the wrong city.

Reporting on this incident has been inconsistent at best. Obviously certain outlets find the whole “the pilots flew to the wrong airport!” angle irresistible. But that isn’t what happened. The pilots, the flight attendants, and their aircraft were dispatched, flight-planned, and fueled for a trip to Edinburgh. That’s where they were expected to fly, and that’s where they went.

The passengers, on the other hand, thought they were going to Dusseldorf. In other words, the plane didn’t fly to the wrong city. The passengers were put on the wrong plane.

The breakdown was apparently between the technical staff (pilots, dispatchers and flight attendants) and the airport personnel who processed and boarded the passengers. The former were Edinburgh-bound. The latter were handling a flight to Germany — or so they thought.

But, you’re thinking, wouldn’t the “welcome aboard” spiel by either the pilots or cabin crew have given things away? We always mention the destination, don’t we? And surely flight attendants would have noticed “Dusseldorf” on the customers’ boarding passes, right? The signs and announcements at the gate, too, would have referenced Edinburgh. Could all of this have somehow been missed?

I, for one, can see it happening. Those PAs are sometimes perfunctory, and how many people are listening to begin with? And I can easily — easily — imagine a scenario where the gate personnel and flight crew found themselves on separate pages, regardless of any boarding announcements or signs above the podium. The fact this was a contract company flying on British Airways’ behalf, rather than an actual BA aircraft operated and overseen by BA personnel, could also have been a factor.

Embarrassing, sure. But not the same thing as two pilots taking their plane to the wrong destination. Which, I’m the first to admit, has happened. More than once…

In 2013, a Southwest 737 destined for Branson, Missouri, instead ended up at a small general aviation field nearby, touching down on a runway less than four thousand feet long. Only a few months earlier, a 747 freighter operated by Atlas Air found itself at the wrong airport in Kansas. In June, 2004, a Northwest Airlines flight from Minneapolis to Rapid City mistakenly landed at Ellsworth Air Force Base. And, in 1995, a Northwest DC-10 touched down in Brussels instead of Frankfurt. And this is only a partial list.

The idea of highly trained aircrews with troves of technology at their behest landing astray sounds, I’ll agree, amusing, quaint, or even patently ridiculous. So how does it happen? Improperly keyed coordinates? A navigational computer gone crazy? Or is there a more visceral, seat-of-the-pants explanation, such as a tired crew mixing up a pair of similar-looking runways.

If there’s a common thread, it’s that often in these cases pilots were flying what we call a “visual approach.” Most of the time, jetliners land using what we call an ILS (instrument landing system) in which controllers guide us onto a pair of radio beams — one vertical, the other horizontal — that form a sort of crosshair that we track to the runway, either manually or by coupling the ILS to the plane’s autoflight system. There are also what we call “non-precision” instrument patterns, in which a GPS-guided course takes you to a few hundred feet or less above the pavement.

But a visual approach, as the name implies, is almost entirely pilot-guided. This is when high-tech goes low-tech. Essentially you eyeball the airport through the windshield, report “field in sight” to ATC, get your clearance and go ahead and land. When available we back-up a visual with whatever electronic landing aids might also be available (an ILS signal, usually), But sometimes our orientation is based entirely on what we see through the window.

Visual approaches are very common, very routine, even at the biggest and busiest airports. Airline pilots perform thousands of these approaches every day without incident. However, you need to be sure of what you’re looking at. This is particularly true at smaller airports, where cues on the ground (roads, coastlines, buildings etc.) aren’t as obvious, and where you might not be familiar with the surroundings. Certain combinations of circumstances make a mistake more likely: a nighttime visual with low-altitude maneuvering, for instance, at an airport you’re not used to, with perhaps a similarly laid-out airport nearby.

In the winter of 1990 I was copiloting a small turboprop when we were cleared for a nighttime visual approach to New Haven, Connecticut. As it happens, the lights and orientation of nearby Bridgeport, Connecticut, appear strikingly similar to those of New Haven. After a minute or two we realized the error and corrected course. All of this happened far from the runway, and, somewhat in our defense, we were flying a 15-seat Beech-99 — a vintage relic from the Age of Aquarius, with as many electronic accoutrements as my mountain bike.

In addition to whatever human errors catalyze such events, weather and air traffic control (ATC), to name two, can lend a hand in getting from point A to, as it were, point C. In the case of that DC-10 finding its way to Belgium instead of Germany, air traffic controllers had been given the wrong information, and began issuing a long and complicated series of vectors and course changes to the crew, sending it toward Brussels. Airspace in Europe is complex and congested, and roundabout routings aren’t uncommon. Thus it wasn’t necessarily obvious to the crew that they were being led astray. By the time the crew realized they were being vectored to Brussels, they decided to land there rather than have to recalculate fuel reserves and orchestrate a last-second re-routing. In the end, it was probably safer to land at the wrong airport than the right one.

The act of landing a plane is, on one level, inordinately simple. At the same time, it’s a maneuver beholden to technology. It can be one, or the other, or both, depending on circumstances: the aircraft type, the approach being flown, the weather, the airport. There are times when an old-school, seat-of-the-pants skill set is exactly what’s required. Other times it’s all but impossible to find a runway without help from the instruments and screens in front of us. Either way, though, it comes down to judgment and decision-making. Despite everything you hear about autopilot and the alleged sophistication of modern jetliners, it’s the fight crew — the pilots — who are very much flying the airplane. Sometimes it takes an embarrassing mistake to make this clear.

Deadly Turbulence

May 28, 2024

LAST WEEK, a passenger died and multiple more injured when a Singapore Airlines Boeing 777 encountered severe turbulence while en route from London to Singapore. The encounter happened over Myanmar and the flight diverted to Bangkok. Then, on May 26th, twelve people were hurt when a Qatar Airways jet hit severe turbulence during a flight to Dublin.

The media is off and running, no doubt triggering panic among the many flyers for whom turbulence is an acute fear.

If you’re one of those people, the first thing I can do is refer you to the turbulence essay found in the Q&A section of this website. You can read it here.

The second is to emphasize the rarity of incidents like this one. Any turbulence encounter powerful enough to hurt scores of people and tear away ceiling panels and overhead lockers, is a frightening prospect. And as climate change intensifies weather patterns and creates more powerful storms, we may see more of them. But they are, and should remain, exceptionally uncommon.

And maybe most important of all, it’s been reported that most, and possibly all, of the injured passengers were not wearing seatbelts. If you’re belted in, even the worst turbulence is unlikely to cause harm. Keep your belt on anytime you’re seated. Crews will often make a PA reminding you to keep your belt on on anytime you’re seated. This is a good example why.

We should also mention that the man who passed away on the Singapore flight died from a heart attack, not from any sort of impact trauma caused by the turbulence directly.

Prior to last week, if I’m counting right, the most recent turbulence-related fatality on a commercial jet occurred in 2009. Before that, a passenger was killed aboard a United Airlines flight in 1997. That’s two or three deaths in a roughly 25-year span, during which close to thirty billion — with a b — passengers traveled by air, aboard tens of millions of flights. Try to let those numbers sink in. This is the kind of thing even the most frequent flyer (or pilot) won’t experience in a lifetime.

What happened is unfortunate and scary, but it’s not a reason to freak out and cancel your flight because the turbulence app on your iPhone shows yellow.

The media focus, meanwhile, has been relentless. An accident in which one person died has received as much attention as a disaster that killed 200 people once would have. That’s not an exaggeration; I can remember when major crashes, in other parts of the world, would be buried on the second or third page of the newspaper. Most people didn’t even know they occurred.

This is one of those “for better or worse” things. It’s precisely because of how rare crashes have become that we hyper-focus on the smaller stories.

Room With a View

March 28, 2024

I’M A SUCKER for a good wallopping view. And who isn’t? A view stirs the soul. It hits those hard-to-reach visceral notes in the way a simulation — a painting, say — can’t.

I’ve seen some spectacular ones: Machu Picchu on a clear day; Hong Kong from Victoria Peak; an unforgettable rainforest panorama from a canopy walk in Brunei; the fantastical mountains of Torres del Paine in Chile; and so on.

Sometimes, though, you want something easy, and that’s where hotel rooms come in. Here, the magic is presented to you, no effort required, to be savored from the comfort of your bed or balcony. It’s thrill and chill at the same time, both exciting and relaxing. I’ll take a three-star room with a view over a five-star room without one, any day.

I spend over a quarter of my life in hotels, at work or on vacation, so I’ve had my share. They tend to be cityscapes, mostly. My favorite of which, thus far, was a nighttime vista of Dubai from floor 60-something of the J.W. Marriott.

But urban panoramas get redundant after a while. It’s the greener settings I prefer. Mountains, oceans, forests. For instance, watching the sun come up over the Serengeti, from a tent at the Ole Serai safari lodge in Tanzania.

And I remember a place in Ecuador, overlooking a valley. It was a hacienda-style hotel perched at the top of a mountain. A floor-to-ceiling window looked out over the town, more than a thousand feet below. And it wasn’t a gradual or tapered descent; this was straight down, a sheer vertical drop. Was it Otavalo, maybe? Or Baños? It was twenty-five years ago and memory fails me. A dig through an old Lonely Planet guide is no help either.

Which is too bad, because the room was incredible. You could sit and watch the clouds sweeping past, below you. Standing outside, the atmosphere made a hissing noise. It was, best I could tell, the sound of the clouds condensing. I have no idea of this is even possible, but I swear those clouds made a noise as they billowed by.

Nothing would ever beat that view, I thought.

And nothing did, until just a few weeks ago, when I stayed at the Ladera Resort on the Caribbean island of Saint Lucia. I’d broken the bank for a winter vacation, and while I expected the view to be special, judging from the online pics, I didn’t expect it to be this special. Stepping into the room, I actually laughed out loud.

It was one of those open-plan rooms with only three sides. The fourth side was a huge, unscreened balcony facing directly toward St. Lucia’s famous Pitons — a pair of party hat peaks, nearly three-thousand feet tall, that are part of an ancient caldera. The private pool was special enough, but it was the view — a sort of West Indies Machu Picchu — that stole the show.

That’s a custom of mine, by the way: immortalizing this or that gorgeous view with my ridiculous feet in the shot. Visit my Instagram stream and you’ll see others. Here’s a more pure version, sans toes.

Imagine feasting your eyes on that, dawn to dusk. I didn’t feel much like leaving the room.

So that’s the new number one. It was also the most expensive hotel room I’ve ever paid for, and to help assuage the guilt of having blown so much money, I think of it as compensation — a reward for all of the shitty and underwhelming views I’ve been stuck with over the years: all those times I’ve pulled back the curtain to behold a parking lot, an HVAC unit, an expanses of urban decay or, as Jonathan Richman put it, suburban bleakness. Heck, in Amsterdam one time I had a hotel room with no windows.

Meditating on the Pitons helps make up for what happened to me last summer at the Pullman hotel in Dakar, Senegal. I’d stayed in the Pullman many times, and my favorite thing about it was the view from the upper floors of the harbor and, in the distance, the famous (or infamous) Goree Island.

It had been several years since my last visit, and I was excited. But when I got to my room, a surprise was waiting. The top photo shows the view from my room in 2009. The lower photo shows almost the identical view in 2023. Speaks for itself. Progress or something.

The curved building with the triangular top is an old property that I once nicknamed “the Graham Greene Hotel,” because it reminds me of the sort of place where the famous novelist would have stayed, making journal entries in a sitting room with potted palms and a ceiling fan.

I was pleased to see it’s still there, and looks like it’s been renovated. The sight of that monolith, however, was devastating.

That’s nothing, though, compared to some other places. Allow me revisit a few…

If I remember right, this first one is a Marriott outside Detroit. Cars, the Motor City… I guess it works, in a way.

From the Crowne Plaza we take in a splendorous HVAC array, with the Atlanta airport in the distance. Traffic, fast food, a strip mall: it’s everything you love about America. In a gloomy overcast to boot.

Is there anything more aesthetically demoralizing than a gas station? Though I guess you can barely see it, with all the ducting in the way. I forget where this was, which is just as well.

A view you can hear. The roar and churn of the cement mixer, some jackhammering, a concrete drill or two. It’s Oakland, California, but I don’t recall the hotel.

The exquisite colors of Phoenix, Arizona. There’s a desolation to this photo that’s strangely evocative. Or not. I’m just trying to make it seem less ugly.

When you think of the island of St. Maarten, chances are this view from the Sonesta isn’t what you picture.

Seen enticingly from the Five Towns Inn, this Burger King is one of many fine dining establishments along Rockaway Turnpike in Lawrence, New York, just outside Kennedy Airport.

And this last one is Newark. Because of course it is.

I’ll add to this list as the misfortune presents itself.

(I need to confess, however, that the last photo isn’t mine. It was submitted by another pilot with whom I was commiserating on this topic.)

And don’t put too much stock in which particular hotels these are. Views can vary significantly room to room. A 40-th floor view from one side of a building might be a lot prettier than a third-floor view from another.

Maybe it’s ironic, meanwhile, to hear an airline pilot going on about views from the ground rather than those from aloft. So it goes, though. As regular flyers know, airplane scenery tends to be muted and indistinct. Altitude sucks away much of the grandeur. I’ve seen some amazing things — the glaciers of Greenland, the Sahara at dusk — but it’s mainly terra firma where the beauty is.

MH 370, Ten Years On

March 19, 2024

TEN YEARS AGO this month, Malaysia Airlines flight 370 disappeared during a routine flight between Kuala Lumpur and Beijing. The wreckage was never found.

There’s a solid chance the wreckage will never be found. That’s unfortunate, but there are clues to work with. And those clues have, over time, led me to believe that the plane was intentionally brought down by one of the pilots, most likely the captain, in an act of murder-suicide. It was ditched somewhere in the Indian Ocean — landed, if you will, on the surface of the sea — where it sank to to the bottom and rests today, undetected but mostly intact.

Early on, I was open to a number of theories popular at the time: fire, depressurization, and so on. Accidents. I’ve come around since then. My opinion is based on the evidence, both as it exists and, just as importantly, doesn’t exist.

If we assume an accident, we must also assume the plane crashed into the ocean. We know from electronic satellite “pings” that the jet continued on for some time after its last appearance on radar. Having suffered some catastrophic malfunction that rendered the crew dead or unconscious, the thinking goes, the plane continued on autopilot until running out of fuel, at which point the engines failed. Without pilots to control the glide, it plunged into the sea.

The problem with this idea is the absence of pieces. There is no way for a jetliner to crash “gently” into the ocean. A Boeing 777 in an out-of-control impact would have effectively disintegrated, producing tens of thousands of fragments: aircraft parts, human remains, luggage, and so on. Much of this debris would have sunk, but much would not have. Eventually, borne by currents, it would’ve washed up.

So why didn’t it?

A small number of pieces did come ashore, but that’s the thing: of the few parts recovered, almost all of them are consistent not with an out-of-control crash, but with a controlled and deliberate ditching. (Even the most textbook ditching at sea is going to cause serious damage and the likely shedding of parts.) The flaperon discovered in 2015 on Reunion Island, for example, and the trailing edge flap that washed up on Mauritius, both from the same wing.

The parts themselves are evidence enough; a thorough post-mortem on them reveals even more. The forensics are complicated, but they’re solid. Use your Google and check out the analysis by former Canadian crash investigator Larry Vance. These pieces tell a story.

For these particular parts to have been found, together with a complete absence of the myriad flotsam a full-on crash would have produced, is to me a smoking gun.

And thus, the biggest reason the submerged wreckage hasn’t been found is because the location of the search area has been based almost entirely on the fuel exhaustion theory. The search-zone calculations, extrapolating from the satellite pings, are based on when and where, approximately, the 777’s tanks would’ve run dry.

Except maybe the tanks didn’t run dry, and the plane went — was taken — somewhere else. What if that was the intent all along — to vanish?

Those pings are still important, and give us hints. Chances are the actual location of the wreckage isn’t far away. But it’s far enough away to have missed it.

I’ve been saying from the start that we should prepare for the possibility of the plane not being found. It happens this way sometimes. If it helps you feel better, the air crash annals contain numerous unsolved accidents. What makes this one different, maybe, is how we’ve come to expect easy and fast solutions to pretty much everything these days, with a fetishized belief that “technology,” whatever that means anymore, can answer any question and fix any problem.

Oh sure, radios, transponders, emergency locator transmitters, GPS, real-time position streaming, satellite tracking. But all of that is fallible, one way or another.

Sometimes nature wins. And that’s what this is about, ultimately: nature. The immensity of the ocean versus the comparative speck of a 777. It’s out there somewhere, in the ink-black darkness beneath thousands of feet of seawater. We’ll probably never find it.

Future Tense

March 4, 2024

HERE’S THE perfect segue from last week’s post. If you missed it, we were talking about the hype and hyperbole that seem to follow every minor incident these days, a phenomenon that I blame, in part, on the dearth of legitimately serious accidents. It often feels as if flying is getting more dangerous, when statistically we’re safer than ever.

To wit, according to the annual report just released by the International Air Transport Association (IATA) 2023 goes down as one of the safest years in commercial aviation history. Not a single fatal accident was recorded involving a commercial jet. Not one.

Combining jet and turboprop operations, IATA says there were 37 million commercial flights last year. Among those, the only deadly crash was that of an ATR turboprop in Nepal last January. If I’m counting right, this puts last year as the second-safest on record, bested only by 2017.

This is nothing if not astonishing. And to glean a sense of how astonishing, you need to flip through the history books. You need to look at the accident archives of the 1960s, the 1970s, the 1980s and 1990s, when multiple disasters were the norm, year after year after year.

For example, in 1985, twenty-seven major accidents killed almost 2,500 people. That included the JAL crash outside Tokyo with 520 fatalities; the Arrow Air disaster in Newfoundland that killed 240 American servicemen, and the Air-India bombing over the North Atlantic with 329 dead.

In 1974 there were ten disasters, including the Turkish Airlines catastrophe outside Paris that killed 346 people. Among the other nine were two Pan Am 707s, two TWA jets (one of which was bombed), and an Eastern DC-9. That’s five U.S. legacy crashes in the same year. Eastern and TWA had crashes within three days of each other.

And so on. Those were particularly bad years, but you get the picture.

I’ve mentioned all of this before. Apologies to those who are sick of me talking about it. But it always bears repeating, because so few people really understand how safe flying has become.

How we got here is also something I’ve discussed in the past. It’s been a combination of things: better technologies, better training, and, believe it or not, better regulation and oversight. For more, see the links below.

And yes, luck has played a role as well. We closed out 2023 with a near-perfect record, but not without a few close calls. Which is what makes posts like this so frustrating. Because sooner or later our luck will run out; there will be another major crash, right here on U.S. soil. As good as we are, we’ll never be perfect. And when it happens, nobody is going to care how long it’s been since the last one. History won’t matter, perspective won’t matter, stats won’t matter. The result will be hysteria and a media firestorm like no other.

It’s precisely because of how rare crashes have become that we’re guaranteed to overreact to the next one. Which is both fair and unfair, I suppose.

When a Wing Comes Apart

February 26, 2024

SO, LAST WEEK, a passenger videoed a damaged wing slat on a United Airlines flight headed from Denver to Boston. Learning of the problem, the crew conferred with its dispatch and maintenance team, and a decision was made to divert the Boeing 757 into Denver.

Copyright issues prevent me from re-posting videos or images, but you can easily Google it. The upper part of the slat, along the front of the wing, inboard of the right engine, appears shredded and chewed. it’s a composite material, and somehow it delaminated and fragmented. How, exactly, is unknown.

Well, no surprise, the pictures are all over media and social media — so much as those things are different nowadays — accompanied by a barrage of terrifying headlines: “Passenger Sees Wing Coming Apart.” “Passenger Horror as Wing Comes Apart.” And so on.

The wing, in fact, did not come part. What “came apart,” if we can call it that, is a portion of a slat. There are several slats per wing, sectioned along the leading edge. Like the trailing-edge flaps along the back of the wing, these devices are deployed in stages to increase lift at low speeds. You’ll see them extended during takeoff and landing, then retracted during cruise.

It’s a terrible look for sure, but the danger here was minimal. One small hazard might’ve been broken material striking the rear stabilizers. Worst case would’ve been the slat breaking apart further, or detaching completely, unlikely as that might be, but even this wouldn’t crash the plane, so long as the stabilizers or tail weren’t struck and badly damaged.

There may have been a discussion about whether or not to deploy the slats for landing. There’s no way to isolate a specific slat, so keeping the broken one retracted would’ve meant a “no flap landing,” where all of the high-lift devices, both flaps and slats, remain stowed. A jetliner can land just fine this way — it just needs to do so at a higher speed, requiring more runway.

A few months ago, due to a malfunction, a 757 I was piloting made a no-flap landing in Colombia. We came in fast, as our checklists dictated (I can’t recall the exact speed), and used about two-thirds of the runway, as our calculations told us to expect. But otherwise the landing was routine. In most ways, what happened to me was more serious than what the United pilots had to deal with, just not as photogenic and so it got no attention.

As it happened, the United pilots deployed the slats and flaps as they normally would, and the plane landed safely. To nobody’s surprise. Certainly not mine.

Segmented slats line the leading edge of a wing, shown here fully retracted. They are operated hydraulically.

I suspect the choice to divert was a practical one as much as anything. Denver is one of United’s biggest hubs, and the plane would need lengthy repairs; grounding it in Boston was going to trigger a cascade of logistical complications affecting hundreds of passengers. In Denver, an airplane swap could be handled expeditiously, with all the needed maintenance resources on site.

Nothing to fret about, all in all. But if the viewer comments on various media sites are any indication, the public is alarmed. “What’s going on in the skies these days?” Asks one reader, his sentiments echoing those of others. “Yet another close call.”

Not really. What’s actually happening is a matter of exposure. These sorts of minor incidents have always been with us. What’s different is the media environment in which they’re occurring. In the old days you never heard about them. Today, everything is photographed and everything is shared. The smallest mishap is on Instagram and other platforms within minutes, visible to millions. A landing gear problem; a compressor stall; a pressurization malfunction. The sky is falling.

Except it’s not. As I’ve talked about in prior articles, major airline disasters are far, far more uncommon today than they used to be. A dearth of them has led to us putting undue focus on relatively harmless incidents instead.

I’m unsure which is more to blame, social media or actual news sources. They seem to feed off one another, so maybe it’s a moot point.

The fact that the 757 is a Boeing model has only made things worse. Thanks to the controversies surrounding the 737 MAX, anything involving a Boeing jet now gets extra scrutiny, deserved or not. No matter that the 757 is a 42 year-old design with an excellent safety record. The B-word is what counts.

Let’s face it, everyone is looking for attention, for views and hits, be it FOX News or the Times or a 16 year-old Instagrammer. Few things, meanwhile, garner more attention or stoke more fear than plane crashes. The mere suggestion of one, realistic or not, is an automatic go-to for eyeballs. And so, here we are.

Dignified and Old

February 9, 2024

So, earlier this week the U.S. Senate’s Commerce Committee shot down the move to increase the mandatory retirement age from 65 to 67. The measure lost by a single vote. Lawmakers succumbed to pressure from the Air Line Pilots Association, which spent months lobbying against the change.

The matter now goes to committee and there’s still a shot it could pass. But I wouldn’t count on it.

ALPA opposed the measure, but many of its constituents, including myself, did not. The union spun the whole thing as a safety issue, and warned of air travel becoming more “complicated” if it went through. The simpler truth is that ALPA has grown beholden to its younger members, who now comprise most of its membership, and who see raising the retirement age as an impediment to their career progression.

Which technically it would be, resulting in slower attrition, fewer upgrades and all that. But it’d be a small one. And these pilots too would have the opportunity to work an extra couple of years at the finale of their tenures, if they so choose.

For older hands like me, there’s resentment. Resentment because the luck and good fortune enjoyed by the newest generation of pilots cannot be overstated.

Entry-level salaries are the highest they’ve ever been. Even at the regional carriers, young pilots can bring in six figure salaries without much effort. Meanwhile at the majors, pilots are zooming up the seniority lists, with some getting captain slots before their 30th birthday. These pilots will be millionaires before age 40.

These same junior pilots skated through the COVID-19 fiasco without a hiccup. Thanks to taxpayer bailouts, they avoided furloughs and in some cases were paid nearly a full salary to simply stay at home for a year. Many took second jobs and collected two salaries.

For those of us of baby-boomer and Generation X vintage, such fortune is difficult to fathom.

In my day, regional pilots were making fifteen grand a year and paying for their own training. Most pilots didn’t make it to the majors until well into their 30s, if they made it at all. After slogging it out at the regionals and a cargo carrier for nine years, I was hired by a major carrier in the spring of 2000 at age 35. Starting pay at the time was around $30,000 a year.

Then came the industry crash in 2001, and thousands of us found ourselves laid off. Those who kept their jobs were hit with massive pay and benefit cuts and elimination of pensions as the airlines went through a cycle of chapter 11 bankruptcies.

My furlough lasted five years. When I finally went back to work in 2007, I was 40 years-old and my salary was about $65,000. That was sixth-year pay. And it was the most I’d ever made in my life.

While all that was going on, the retirement age was bumped from 60 to 65. You think two years is a drag chute on your career progression, try five. But we dealt with it, and now we too can work until that age.

Long and short, we have some catching up to do. Those two extra years would be a huge help. The money, the health benefits.

New-hires in 2024 are earning in their first one or two years what it took us a decade’s worth of seniority to make. Projected over a thirty or forty-year career, the earning potential for a pilot hired today is absurd. Adjust for inflation all you want; the differential over any length of time is huge.

Wars, recessions, and any of a dozen other calamities could set the industry reeling yet again, it’s true. But that doesn’t offset the tremendously good fortune the newest pilots are currently basking in. My peers and I faced those same risks, but without the front-end benefits of today’s generation. Things might go sour at some point, but if nothing else they’re making fantastic money in the meantime. For us that wasn’t the case.

The younger gang is having its cake and eating it too, frosting and all. Maybe it’s human nature; call it selfishenss or self-interest. If I were in their shoes, what would my vote be? Still it feels greedy, even petty, as one generation of pilots prevents its predecessors from making up lost ground.

Better Things to Talk About.

January 8, 2024

POOR ALASKA Airlines. There they were, leisurely mulling the finer points of their merger with Hawaiian, wondering which visage to paint on the tail, when the 737 MAX-9 stole the show.

Pop went a fuselage plug on flight 1282, decompressing the jet and scaring the daylights out of everyone on board. The plane landed safely, but now a number of MAXes are grounded as regulators focus on attachment bolts.

The MAX can’t catch a break, either. This is the plane that spent two years on hiatus after the crashes of Lion Air flight 510 and Ethiopian Airlines flight 302, until its twice deadly stall-avoidance system was redesigned.

It looks bad, I know. Particularly for Boeing. But this is likely a lot more minor than the media spin suggests. I expect the plug attachments will get some sort of do-over and the planes will quickly be up and flying again.

A jetliner is pressurized so that its occupants can breathe without the need for supplemental oxygen. If the fuselage is breached, that squeezed-together air rushes out. The pilots will don oxygen masks and take the plane to a lower altitude in what we call, plainly enough, an “emergency descent.” The sensations of this drop might be alarming, but it’s an easy and straightforward maneuver.

Rarely are decompressions deadly. When they are, it’s usually because it happens explosively, such as when a bomb goes off, causing massive structural damage. In the Alaska incident, the big danger would’ve been the door plug colliding with the tail structure. But this didn’t happen, leaving the rest of it pretty routine.

I don’t mean to sound blithe, but it’s amusing how much attention this mishap is getting. One of the biggest news stories of the week is about a decompression in which nobody was killed or injured. The track record of the MAX, I figure, is part of the reason. A negligible malfunction, or a design flaw suggesting negligence? Let’s hope it’s not the latter, but either way, back in the Golden Age of Air Disasters, something like this would barely have made the papers.

Ironically, the amount of coverage we’re seeing serves to remind us of just how safe flying has become. In decades past, multiple airline crashes were the norm every year, with hundreds dead at a time. We’ve grown so accustomed to near-perfect safety that a minor event, without a single injury, wins as much attention in 2024 as a crash that killed two-hundred people would’ve gotten in the 1980s.

On the other hand, it’s better to be reading about a decompression than about a catastrophe. And it hardly needs saying that this could easily have been more serious. Had a passenger been sitting adjacent to that plug and not wearing a seatbelt, he or she would’ve been ejected. A hole opening up in the side of a plane, regardless of the reason, earns more than a shrug. Even more so if the problem is traced to a design defect or a quality control screw-up. People are skeptical, and let’s be honest, both Boeing and the 737 MAX deserve whatever scrutiny they’re getting.

I guess that’s the real, if obvious issue: It’s less about what happened than what could have happened. And will it happen again?

Incidents like this, and our focus on them, keep us on our toes. I get that. It’s a way of being proactive and careful, so that we maintain the levels of safety we’ve achieved.

UPDATES:

Some of you have wondered why section of the Alaska 737 that blew out was shaped like a door. The number of required doors depends on seating configuration. Alaska’s layout doesn’t mandate a door in this spot, so there’s a plug there instead, attached with bolts.

Meanwhile, a news outlet today asked me why, following the decompression, no announcement was made by the captain. It’s hard to know, but I imagine the cockpit crew was quite busy. There was an emergency descent to perform, as well as the necessary checklists, coordination with air traffic control, etc. Also the pilots would’ve been wearing oxygen masks, which makes communications more difficult.

It’s possible one of the pilots did make a PA but it wasn’t heard in the noise. Or, being as busy as I imagine they were, they may have relayed information to the flight attendants and left it up to them.

As a pilot I’ve experienced a handful of depressurizations over the years. One afternoon I was working a flight from South America to the United States when, high over the Caribbean, came a sudden whooshing sound that seemed to emanate from nowhere and everywhere at once. I could feel my ears popping, and sure enough, a glance at the instruments showed we were quickly losing pressurization. The captain and I put our masks on, took out the book and began troubleshooting.

Part of that troubleshooting involved one of those steep descents. To the passengers I’m sure it
felt like a roller coaster, but everything was carefully coordinated. The autopilot was engaged the whole time, and no limits were exceeded.

Should a pressure loss occur over mountains or other high terrain, pilots will follow predetermined routes, sometimes called “escape routes,” that allow for a more gradual descent, in stages. Even if crossing the Andes or the Himalayas, there’s always the opportunity to reach a safe altitude before supplemental oxygen runs out.
