RE: Air Marshalls on U.K Flights

With the new doors in the event of single pilot incapacitation the remaining pilot would notify the cabin crew and grant them cockpit access. In the event of dual pilot incapacitation there is a procedure that allows the cabin crew access to the flightdeck but I shouldn’t really divulge too much in that direction. All I can say is that if either pilot is concious in the flightdeck under the new system it is theoretically impossible for anyone (including cabin crew) to gain access without permission.
