I doubt very much that there was any real deficiency in the required level of security. That level is not designed to stop this sort of crime. We have seen a student steal a C-150 he was sent out to pre-flight for a lesson, for Heaven's sake! What should we do, handcuff them first?
Somehow, I fail to relate the theft of a light aircraft trainer with a transport airplane at a Part 139 airport.
