I would also hazard a guess that more incidents have been caused by problems being missed on a night sortie preflight due to the inadequacy of the 'issue' RAT than there have been because a none issue flashlight has been mislaid. When I became aircrew the watchword wasn't FOD or controlled tools it was 'integrity', so yes I believe most aircrew would own up to mislaying an item, or they would have done in my day.
