Battery fire, taking out essential busses first, crew incapacitated by insidious fumes and confusion (thousands of hours and nothing has ever gone wrong for them), jet randomly deadsticks until crashes in remote location in Indian ocean? Cabin crew don't enter cockpit because of muslim culture and knowledge that pilots are 'playboys' and may be 'busy'? Crash locator fails to function. Third world air forces (Malaysian, Thai) culturally incapable of responding to or taking seriously radar returns of unknown aircraft.
