Fire, probably. But also, how complicated would you make the system if you needed to prevent certain switches from working during certain times of flight? At some point... we're all just in the hands of the people in the cockpit.
I can't put my car into reverse gear while driving down the freeway.
Earlier quoted context omitted.
even though that raising the gear is a up motion and fuelcut off is a down motion?
And fuel cutoff is _two_ down motions? That's the death knell for this theory, imo.
Instead, it's that because muscle memory allows you to do things without thinking about it, you can get mixed up about which action you meant to perform and go through the whole process without realizing it.
Earlier quoted context omitted.
It could be defective switch springs, fatigue-induced muscle memory error, or something else. The pilot who did it saying he did not may not have realized what he did. It's pretty common under high workload when you flip the wrong switch or move a control the wrong way to think that you did what you intended to do, not what you actually did. That said Boeing could take a page out of the Garmin GI275. When power is re…
When your engine catches on fire/blows apart on takeoff you want to cut fuel as fast as possible.
But I'm an advocate of KISS. At a certain point you have to trust the pilot is not going to something extremely stupid/suicidal. Making overly complex systems to try to protect pilots from themselves leads to even worse issues, such as the faulty software in the Boeing 737-MAX.
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…
There is no possible way to confuse these two actions. There's a reason a wheel is attached to the gear lever.
Test your mental model against the real world. This is your opportunity.

At least it worked for me on Kerbal Space Program. At least sometimes.

Me: “The build is breaking right after you checked in. Why did you do that?” Him:”I did not do so.” Me: “The commit shows it as you. And when I rolled back everything builds.” Him:”It must have been someone else.”
That person was really annoying.

Remember that incident where a cop pulled out his taser and tased the suspect? Except he pulled out his pistol and fired it.
The taser looks nothing like a pistol, feels nothing like it, yet it is still possible to confuse the two in the heat of the moment.

The only solution I can think of is emergency parachutes. Like lots of them. would also be useful for other types of in air engine/control failures. At least it worked for me on Kerbal Space Program. At least sometimes.

The Cirrus system is deployed by rockets, allowing it to function at a very low altitude. They say that you should deploy it no matter what altitude you are at, and it will add at least some friction. The system has a very impressive track record.
However, at this altitude, with an airplane this heavy, you might have to put the rockets on the plane to decelerate enough to save lives.
