crew rage?
From AirDisaster.com News (Cut Version)
A dispute between security guards and crew on board an Iran Air flight about a passenger visiting the cockpit caused the pilot to divert to Frankfurt because he didn't have the morale to continue.
I don't know when this incident happened so I apologise if this is out of date!
I thought crews were supposed to get on with each other! What do you do if you get stuck on a long haul flight with someone you don't like?
