Me, not long. Not even a year. But, I had to stop last year because I ran out of money.
Haven't flown since.

I'm attending everglades university majoring in aviation technology. Why didn't I go for professional pilot? I don't need FAA licesnes to graduate!
My academic advisor is an IFR rated pilot, one of my teachers flies Gulfstream IV, V, and another teacher is a retired ATP, ex-747, 727, 707, DC-8, etc. I have him next month for AERODYNAMICS! YES!!!!

I love flying!
