On the door of my Cub there is a placard that says: GET IN, SIT DOWN & HOLD ON!  8-)

The first plane I ever flew was a J-3 Cub. First FAA license was a student pilot's, then I got my Private pilot license in ASEL (airplane single engine land). The next rating was Instrument, then Commercial followed by Flight Instructor. I built up my time as a flight instructor and doing some charter flying. When I was hired by the airlines, they sent me to their school to get my Flight Engineers rating in turbojets. Big jump from ASEL! First plane I flew as F/O was the 727, which at the time was considered center line thrust so I still did not have a multi-engine rating. It was not until I checked out on the 767 that I got my multi-engine rating and ATP all at the same time.
