How about this for a scenario (one I have done myself in fact):
Pilot needed to open a hatch or similar, did not have a screwdriver, looked around the hangar, found screwdriver in trainees open toolbox, "borrowed" it. Got distracted doing something else and forgot about the screwdriver. The rest is history.
It just strikes me that this is a payout based on very scanty facts in fact mostly surmisation.
