Well kingneptune, you'll be happy to know - it did happen! Not in an Hog tho' - in a tiny little A4 Skyhawk.
Place: El Toro MCAS (not there anymore:() Time: oh, about 25 years ago.
One of the maintainers who had high aspirations to go to flight training found out that his dreams wouldn't come true, so... on one sunny California day he decided to make it happen:pilotfly:
He took a little Skyhawk for a spin... not too far, just flew around, landed
and was escorted to a "career change" ceremony.
Don't ask me how he was able to start, get to active and so forth...
It did happen! He was an aviation fanatic and spent a lot of time in a sim.
(A4 I imagine)
