Interesting point Victor Tango. I'm not convinced that this is a simple as it's being made out to be.
As for the logic behind wanting video in the cockpit, Lone Wolf; no, that would not have stopped this tragedy, but it would certainly have helped unpick what happened. It could have been seen whether the FO did alter the altitude dial - or indeed whether he was even conscious. SauvignonBlanc; Obviously the storage would have to be inside the FDR
As a passenger, I couldn't care less whether pilots are upset by a 'lack of privacy'.
Privacy ?? What on Earth do pilots need privacy for on the flight deck ???? If you are in total control of my life and that of my family, being as you are, in command of a metal tube six miles up in the sky, hurtling along at 500mph, I want everything you do visible, checked, cross-checked and scrutinised.
Privacy is not an option.
