(svn r15665) -Fix (r8973): Handling of aircraft crash counter did not take account of the reduced number of calls (from 6 down to 2) to the aircraft event handler, resulting in crashed aircraft taking three times longer than they should to clear. Compensate by increasing the counter by 3 on every call instead of 1.
