Count how many life jackets were inflated before the idiot left the cabin for a start
Idiot?
Well I don't know about US Airways, but I flew five United Airlines flights last week and I listened to the safety brief every time. Without exception in the context of a water landing the recorded brief played on the IFE / PA said "inflate your life jacket just BEFORE exiting the cabin". Maybe more folks listen to the safety brief than you think!
