Am I the only one who thinks that if the 'pilot suicide' line currently in favour by many commentators turns out to false (as I suspect it is), we may well see all airlines forced to adopt what I think is already the El Al system where the pilots are totally isolated from the cabin for the whole flight? (Does El Al allow a small servery hatch for meals, or is everything the pilots require, including food, put in with them before the flight?)
If this happens, God help us all! I'm pretty sure FAA will come up with another idea though, as locking up the pilot and co-pilot together in a box for a 12hr flight, while being in charge of the aircraft and everyone on board, is simply inhumane.
