I think we are all underestimating the importance of having less than 100 ml of liquid; because, although the pilot only needs his "bare hands" to kill everybody on board.....he'd probably need the other pilot to be away from the control stick to do it, so.....
With sufficient fluid, if one pilot got the other pilot to drink it, he could "trick" him into going to the toilet and
, voila, the airplane is available to be crashed.
So as you see, we should all abide by and respect the 100 ml of fluid rule!
