He may not be on the same level as Chesley "Sully" Sullenberger, but to the passengers of Thomas Cook flight TCX9641, the aircraft engineer travelling on board was a true hero.
After learning that the aircraft was experiencing a technical problem that would require an eight hour delay, the as yet unidentified passenger came forward claiming to be an aircraft engineer that was qualified to work on the Boeing 757-200. After following strict procedures to confirm his credentials, the man was allowed to work on the plane. In the end, the Thomas Cook flight arrived at its destination only 35 minutes late. Needless to say, I'll bet you can think of a personal situation where a dude like this would have come in really handy. [BBC via Slashdot]
