Would there be a scenario where the pilots could've been disabled w/o the pax's knowing about it? Considering Bill Palmer's scenario, AP flies on its own into open ocean, runs out of fuel, drops - by the time pax's realize what's going on and try using cell phones there is no comm - no cell towers in open ocean. Have to consider that most people go to sleep asap in red eye flights, and that the probability of someone with a sat phone is a possibility but how likely?
