I think I might be genetically pre-disposed to liking aviation
When I was born my Dad was working as a pilot for the Cessna distributor in Australia, so I've been around aircraft since before I can remember and many of my earliest memories are of aircraft, including going to the local aerodrome with Dad (after we'd moved from Sydney to the bush) to watch the Fokker Friendship service come in. I'm no psychologist but I guess that when I'm working on aircraft I'm a child again, standing with my Dad (who died when I was in my teens). I cannot concieve of doing anything other than aircraft maintenance for a living; I even do it in my spare time, working on vintage aircraft and warbirds, so you could say I am getting paid to do something I would happily do for free.
Oh, and I love being airborne too, going someplace new or seeing something from above, revelling in the physics of flight, the sheer beauty of flying between cu-nims on a bright moonlit night, the city lights.... anyone who comes to Sydney MUST take a night flight over the harbour. You can book a seat on a DC-3 and sip champagne while admiring the view. How good is that?!
Monty Python's Flying Circus has nothing to do with aviation, except perhaps for Management personnel.
