So you're telling me that those switches don't have a voice that says "fuel cutoff switches transitioned" like in the movies? That's bad design

WHOOP WHOOP TERRAIN, TERRAIN! PULL UP! PULL UP! (WHOOP WHOOP)

Wait till the final report is out and what resolution they come up with then we'll see who the joke is on

it makes sense to me that the pilot who said "I did not do it" actually did do it without realizing it, was supposed to be putting the landing gear up when he committed a muscle memory mistake. it happened around the time the landing gear should be up, and this explanation matches what was said in the cockpit, and the fact that the landing gear wasn't retracted. I think this idea was even floated initially by the you…

One of the nice things about finally having the preliminary report is I get to stop hearing all of the same assumptions/theories/YouTuber said/"a guy I know got a leaked report"/etc in water cooler talk at work because the preliminary report solidly disproved all of them so far. If anyone even had and stuck with an idea matching this report it wouldn't have stood out in the conversations anyways. The collection of co…

This was a really disappointing incident for aviation YouTube - I unsubscribed from at least three different channels because of their clickbait videos and speculation.

It is known that the switches cannot effectively be flipped by accident. It is known that the switches were set to "cut-off" because they were then later restored to "run", so it was not an electrical fault (i.e. switches pointing to run but reporting cut-off). Pilot dialogue and engine telemetry confirms the cause of power loss was fuel cut-off. The question I can't help but think is how did the pilot realize it was…

Given what you're vaguely implying -- that the switches would be nowhere near the first thing a pilot would normally think of in the kind of situation -- what are the odds the pilot asking on record "did you flip the fuel cut-off switch?" is the one who actually flipped the switches and was simply trying to fool the would-be investigation (even knowing they all are about to perish)?

I'd say the odds are 50%. The odds of the opposite scenario - where the pilot who said "did you flip the fuel cutoff" wasn't the one who did it are also 50%.

Based on the cutoffs for both engines being flipped 1 second apart, the above exchange being caught on the CVR, and then within 10 seconds the (presumably the other) pilot switching them back to Run, it's pretty clear that this was a deliberate act.

shows you the switches on a 787. They are protected and hard to futz around with by mistake.

> Context is both these switches being turned off with a 1 second gap. Doing it with one hand simultaneously would possibly explain it It would. So would switching both quickly in succession. One second is a long time—I can adjust power, prop, fuel pump and flaps in about that time.

What I gathered from comments here is it's not a simple flick of the switch and it actually takes some effort to turn them off. Can you really do it twice within the span of 1 second?

You pull it out and flip it. It’s not easy to do inadvertently. But it’s also not convoluted—you want to be able to quickly cutoff if there is an engine fire.

The pilot wasn’t flying an unfamiliar aircraft.

I think the aircraft being familiar makes it worse: if you're used to going through a certain motion to do a thing, it may be one of things your brain can do without really thinking about it much, which is where the danger comes in. I've engaged my wipers when meaning to shift gears before, in my truck which has a steering column shifter. After driving the truck for years. I have ADHD and I very often let my brain go…

If your wipers had the equivalent of a child safety cap it would be hard to do it accidentally, especially twice in a row.

I agree, there's a significant distinction between "the switches were (physically) flipped" and "the circuit was opened/closed". In this case, it may be a moot distinction, particularly if no physical evidence of fault or tampering has been discovered in investigation. But, in theory, very important - there's a lot of potential grey-area between the two statements. The proximity of the incident to the ground may also…

My understanding from what we've been reading is that these are physical switches that cannot be moved using remote triggers. Wildly speculating, there _may_ be a possibility that the _effect_ of the switch may be triggered remotely, if it's a signal being read by a control unit or computer of some sort that then actuates the specific electromechanical components. But it would seem impossible to move a physical switc…

Any switch becomes irrelevant if a saboteur has access to the behind-the-panel wires that the switch operates.

But I presume that would leave physical evidence which would have been discovered by now. Presume, but cannot be certain.

Looking at the transcript, it seems to confirm the link I posted, that there is a path back to flying, and that the FAA approves antidepressants.

It's human nature to want to guess at possible explanations for things that are unusual and unexpected. If hearing those guesses annoys you, nobody is forcing you to read through comments on a thread of people making them! (I hope - sorry if you are being forced after all.)

> If hearing those guesses annoys you, nobody is forcing you to read through comments on a thread of people making them!

It’d be nice if we could only read insightful comments, and unread the wacko comments, but we can’t. This discussion has actually provided a lot of useful comments from people who seem to know what they’re talking about, but also a lot of really wild speculation.
