Report says the switches went to cutoff one second apart from each other. Can a human do the physical operation on two switches that quickly?

The timing is really curious. 08:08:35 Vr 08:08:39 Liftoff 08:08:42 Engine 1 cut-off 08:08:42 Engine 2 cut-off 08:08:47 minimum idel speed reached ?? One pilot to other: why cut-off. Other: Did not do it 08:08:52 Engine 1 run 08:08:52 Engine 2 run 1 second to switch them both off and then 4 seconds to switch them both on. No one admitted to switch them off. They are probably going with fine comb over the audio and al…

Well in the murder-suicide scenario it makes sense for the culprit to turn them off as quickly as possible. The longer time to turn them on could plausibly be a struggle or simply needing to fly the plane while reaching for each switch individually.

This implies intent.

To me this reads like an unintentional error with colossol implications.

Are you suggesting there was malicious intent and then a delibrately crafted denial by the perpetrator?

Is there a possibility that they got hacked and remotely toggled ?

Sadly not. It’s a physical switch with no capability of a remote toggle. The flight data recorder clearly shows one was toggled off within a second of the other, which rules out almost every non-intentional scenario.

There's a good photo of them here; https://theaircurrent.com/aviation-safety/ai171-investigatio... You can do them both with one hand.

Are you completely sure you can considering that they are spring loaded and they are like 7-10cm apart judging by the size of other controls?

I don't understand your question. I have done this myself, am I completely sure?

I don’t understand this part of your post:

> This was not suicide, or murder-suicide; it was one of the most horrific mass murders in history, in which the guy that did it happened to lose his life in the process.

Why wouldn’t this qualify as a murder-suicide, assuming your theory is correct?

Do you know if the mechanical position of the switch guarantees its electronic state without any possibility for hardware malfunction? If no, then you are claiming a person made one of the most grave acts of inhumanity ever. This sounds to me like an electronics issue - an intermittent, inadvertent state transition likely due to some PCB component malfunction

I am, and I’m willing to stake my reputation on it. If I’m wrong, I’ll hang up my hat and never cover live news again.

Pilots are drilled from day one that the fuel switches are sacred. After a few accidents where one engine failed and the pilot accidentally turned off the remaining functional engine, the training was overhauled so that it would be impossible for it to be an easy action done by mistake. One pilot is required to ask the other for confirmation before toggling the switch, I believe. It wouldn’t be something you’d do from muscle memory.

I mean lots of people in prison say they are innocent
