At 200 hrs I thought I knew everything about how to fly an airplane....
Same at 400, 800, 1600, 3200, 6400 hrs etc.
Thank god I finally got enough experience to realize I'm an idiot.
Btw....My experience with folks who leave a successful career to pursue thier dream of avaiation......has been less then stellar.
I'd venture the opinion that Beech V-tails have proved.....being a brilliant doctor doesn't make you a brilliant pilot....
