Should flightdecks be kept locked?
Following the horrific events in the recent terrosism in America, I cant help but feel that this should surely be the final warning that something drastic has to happen in order to safeguard against the hijacking of aircraft. When an aircraft can be turned into a 100 tonne missile is the answer to simply dissallow all access to the flightdeck and install video cameras at the door so as the pilots are able to see any activity outside the door?
