I graduated with an aerospace engineering and mechanics degree, emphasis on propulsion. Focused on internal combustion engines. This was the late '80s, I'm sure Geeto can tell us just how thriving the piston powered general aviation industry was in the late '80s... what can I say, I went after what I was interested in, not what was easily marketable. After two years of looking for a job I got into the auto industry and never left.
It was a lot more fun back then than it is now, I'm biding my time until retirement at this point.
