28. And like cpxxx says, I'm not known for my diplomatic skills. I'm not one to talk from a great wealth of experience from decades of flying because I don't have either. I just hit 10 years, 4500 hours of which only 500 were spent instructing. Traffic reports, skydivers, charter flying, airline, and corporate flying have paid the bills (the airline just didn't cover all the bills). In fact for the last 3-1/2 years I've been and still am to my knowledge the youngest pilot on a very well known charter certificate. Starting in line service and an online degree program gave me a leg up on those who go to university for their education and ratings by allowing me to do so while working/flying full time.
Now when I do instruction it's usually more advanced training such as basic aerobatic, tailwheel and instrument refresher stuff for weekend warriors and well to do folks who don't have the opportunity to stay proficient in their airplanes as they'd like.
Anyways I write like a crotchety old bastage on occasion but it's only because those darn kids won't get off my lawn...
