The co pilot opened the cockpit door??????????????????????? Say it isn't so! What the heck was he thinking?????????????? He should be fired immediately.
I'm still under the impression, due to the live interview with a passenger who was there, that the bottom half of the door was kicked in...
I concur with you however, that if that door was intact and opened...whoever opened it should be fired.
Maybe he had to go to the men's room.
