That example is so well known due to how exceptional it was, especially how the pilots handled it. Robert Pearson, the captain, was a very experienced glider pilot. That's something that not many commercial pilots have. There were also two factors in the landing, that allowed for this to happen. You're going to be coming in really fast for a landing, when gliding in a commercial jet, and you don't have access to your…

The "scraping helped slow it down" theory makes no sense to me. What do you think has a higher coefficient of friction - tire rubber on asphalt, metal on asphalt, or metal on metal?

I would hesitate to chalk it up to just theory, given it was in the NTSB report and they don't really mess around with throwing baseless stuff around. I'd be interested to take another look at it. They likely go into the material science and physics behind this very thing. They're usually filled with gems.

You also have to keep in mind, it wasn't just rubber against asphalt, it was rubber on a wheel that spins. I'm not sure if the front nose gear on a 767 has any brakes but even if it did, I can't imagine it would be sufficient at the speeds they were going.

The point is that the unions are there to allow the pilots to advocate for all kinds of safety-of-flight related things like fuel reserves, crew rest, and so forth that management would be happy to cut to save money. And to do so without fear of retaliation. And if you don't think the airlines would love to lobby Congress about the regulatory backstop, well . . .

I think the literal fear of death _might_ be motivation enough for pilots to advocate for safety? And if they want to fire you, would you want to work for them anyways?

Famously, this fact is also why no one drives recklessly and no one has lost any limbs with power tools.

Quick note that Preswick is not really Glasgow (35 miles away) and Glasgow has its own airport which presumably was also affected by the same weather so they couldn't divert to that. Between the Scottish lowlands (where they had already tried all the commercial airports) and anywhere else, Manchester is about the closest option.

As someone totally ignorant of British airports, a Google maps search for "airports northern england" shows Teesside, Carlisle, and Newcastle all significantly closer to Edinburgh than Manchester. Are these not places where a 737 under emergency could land? Or was the weather also bad there?

> Or was the weather also bad there?

That's likely, these places are not very far apart, and weather systems that cause 100mph winds don't tend to be small. And presumably if you have at most one landing attempt remaining you don't want to be taking any more chances.

> Between overworked, understaffed ATC and undertrained pilots, I'm expecting some major disasters in the coming years. Maybe in the US, but this story is based in Europe, each country maintains a regulated standard and there are no EU wide disruptions that have ever happened to the best of my knowledge. Also Ryanair don't travel transatlantic flights.

Three weeks ago in Nice, France it was a fraction of a second away from two A320s crashing [0] and possibly hundreds of deaths, similar to Tenerife disaster [1]. Investigation is ongoing and many factors are at play (bad weather, extra work for ATC due to that, confusing lighting of runways etc) but also, from French media reports, there used to be 15 people per shift 5y ago in Nice ATC, now there are just 12, and tr…

Mistakes and disasters happen, unfortunately the safety we have while flying today has been written in blood, but there is no major understaffed ATC and undertrained pilots in general as mentioned.

15 down to 12 in 5 years with more traffic is not out of the question with advancements in technology but of course, if there is a report that shows understaffing then absolutely it should be addressed straight away and it will be, by the French government.

Management can't cut fuel reserves, not because the pilots are unionized but because there are some very strict rules about these fuel estimations prior to take off and margins be damned. And those rules are exactly there because otherwise this kind of incident would happen far more frequently. But it's regulation that is the backstop here, not the pilots.

...that regulation is text in a database. It can be changed capriciously at any moment, like they often are. It takes people with ideas and a willingness to put pressure in the right places to be sure that sane policies prevail. I think it's pretty obvious that as time moves forward, we need to rely on "regulations" less. The root and history of the word in the political context is to make things regular. But state a…

I think the thing that's being pointed out as overlooked when praising the employees and the unions, is the regulators, who are the people who play a very large part in making sure that the regulations are enforced. The regulations are just text in a database, but it's the regulators who actually make it happen. A pilot who wants to push back against a beancounter cutting corners has a union and a regulatory agency to back them up.

"I’m a little confused by what there is to investigate at all." You're confused why they should investigate how everyone on that flight came within minutes of dying? Something about the fuel reserves, procedures, or execution was clearly flawed.

Fuel depletion is risky, but not that risky; see the Gimli Glider for a case much more dangerous than this, which still worked out amazingly well. Edit: Here is the Wiki on incidents... https://en.wikipedia.org/wiki/Fuel_starvation_and_fuel_exhau...

I know you're trolling, but for anyone that hasn't heard of Gimli Glider, look it up or watch a documentary on youtube. The stars definitely aligned to make that happen.

If they have to touch and go, how long would it take until they get the plane around for another approach? In fact, you might not get as far as that touch and go and have to go around. You need some margin for all of these eventualities. The likelihood is low that these happen, but they have to be accounted for.

Sure, but the flight was a lot longer than planed. How much extra do we need. They declared an emergency, and thus put themselves at the front of the line. They had 6 more minutes to do that touch and go around if that happened, and since they were already in a low fuel emergency they get priority and so there is enough time to do that if they needed. (edit - as others have noted, 6 minutes with high error bars, so t…

How much extra do you need? Enough that a pilot/crew doing their job properly will never run out of fuel and crash.

So yes they will do an "investigation". It's not a criminal investigation. It's to understand the circumstances, the choices, the procedures, and the execution that ended with a plane dangerously close to running out of fuel.

This will determine if there were mistakes made, or the reserve formula needs to be adjusted, or both.

Don't tell me about cost, just stop. Let MAGA-Air accept some plane deaths to have cheap fares.

Can anyone say whether airline pilots make each diversion decision solely based on their own information and judgment, or do they loop in the company?

Sure, company dispatchers are usually part of the conversation, and in non-emergency diversions (i.e. the vast majority), they may suggest specific airports that would be more convenient for company logistics. But the final decision is always the pilots' - and once they've declared an emergency, more or less every single airfield, including military, becomes available to them.

You get that energy back on descent, no?

4 replies and 3 are dismissing even the idea.. Yes, you get "some" back, and its not negligible amount. Typical modern airliner can descend on 15-20:1, giving you over 150-200km (90-120mi) range from typical cruising altitude of 33 000 feet even with engines off. Most everyday descents are actually done by maintaining altitude as long as possible, and then iddling the engines fully for as long as clearance allows. (O…

That is very exceptional. I've written fuel estimation software for airliners (cargo, fortunately), and the number of rules regarding go-arounds, alternates and holding time resulted in there usually being quite a bit of fuel in the tanks on landing, by design. I've never heard of '6 minutes left' in practice where it wasn't a massive issue and the investigation into how this could have happened will make for interes…

Naively as an outsider, this situation seems like everything worked as intended? On a nominally 2h45m flight, they spent an extra 2 hours in the air, presumably doing doing fuel intensive altitude changing maneuvers, and were eventually able to land safely with their reserves almost exhausted. I’m a little confused by what there is to investigate at all. How much fuel should they have landed with?

ideally, enough to divert to another airport, in the off chance something happens, like a pending emergency at point post.
