Locked cockpit would prevent passenger reaction and if both pilot and co-pilot like the idea of killing a plane full of people for ‘Allah’-what’s to stop them? Then again, Third World maintenance could play a part, not to mention good old incompetence. Either way, I doubt a Muslim country would ever give us the truth and-I’m not ashamed to say- a few hundred dead Muslims is a good start.( Pity reserved for any non-Muslims aboard)
If you put an airplane in a parabolic dive everyone will float around in zero g unless you are buckled into your seat. Do you know what the Vomit Comet is?
