Learn something new every day. Awesome tip! More than once I've wanted to see what the hits looked like from the outside.

Yes, usually the online servers as REPKA use this script, which renders a plane abandoned by a player useless by damaging certain parts... fuel pumps, engines, elevators... therefore the moment you leave your plane by ALT-F2, the plane gets damaged by script and crashes or will be destroyed by the script after a timeout defined by the server. So you should only use ATL-F2 after the end of your sortie on the ground. ;)
