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 I'm right, you can see why the airlines are so keen to accept the pilot suicide line, for any such moves will cost a fortune to implement, with precious First Class revenue space lost as the security door is moved aft to incorporate a toilet, a mini galley, and for some airlines - (many of you will know the one I'm talking about) - a pilot rest area.
Can you imagine what that would be like on ultra long haul, with two crews cooped up together for fifteen hours in what I know will be the smallest area the companies can get away with providing?
