I've considered the possibility. I'm at a point in life where I'm thinking about The Second Career.
I honestly don't know much about the process, the job field or the earning potential. And it's not like I'm a master mechanic - I'm just reasonably handy with tools and I'm not afraid of machinery or motors, even if I'm not particularly well-versed. I suppose I'd be cynically described as "knows enough to be very dangerous." Thus, my line about having someone teach me how to wrench on an airplane.
I like the idea of spending my days at airports fixing airplanes and being around airplane people and communities. But I also know that a) I probably have a romanticized notion of it, and b) like anything else, it eventually becomes a job. Maybe a good job, maybe a job I'd enjoy, but a job nonetheless. Not ready to shatter my illusions, I guess. Still plenty of money to be made in the field I'm in.
