Been mentioned before, but AFAIK they've never been delt with.
It's been a while but from what I remember if your flap is shot off it isn't really shot off, it just shot off visualy and is physicaly jammed in the position it was in when it whas hit. They should either not fly off visualy when this happens or disapear completely. Also, apparantly they are prone only to jamming and never anything els, beause you can fly 600 mph and they will never break off. They should either break off or have auto-retract done away with completely.
As I said it's been a while, and I don't actualy remember if flaps can be shot off visualy and physicaly, but I do know (if this hasen't been delt with yet) that no amount of speed can damage them the way they are now.
