As a student pilot in the 1980's I swapped flight hours for fueling, cleaning aircraft and mechanics helper duties at the local FBO. One of the aircraft renters slid a wooden wing Mooney into the home runway without lowering the gear. The FBO AP/IA owner was a crusty old dog who relished in giving the FAA fits, so he drove to Texas from Idaho and bought a used wing from someone and mated the fuselage to the wing, which he never documented in the logs!. In the process the airplane was completely stripped down and one of my tasks was to sand off the zinc chromate off all the tubes before repainting them. The tubular chromoly fuselage cage reminded me of the funny car dragsters I worked on with my older brother and his buddies. Also it looked like the frame of the P51 models I built as a pre-teen. That was enough for me to realize the designers were interested in strength and protecting the passengers in the event of a crash. About the time the Mooney was ready to test out I acquiring my PP certificate (in the P and C brand aircraft), I got to do the taxi test runs of the rebuilt Mooney (my first time operating a Mooney) doing sequential ground runs up and down the runway and working out the known squawks. Finally the owner IA decided it was ready to go around the around the patch and I expected the lead instructor to perform the flight tests. To my surprise and (foolish) acceptance the owner IA said I could fly it around the patch for the first flight! I memorized the POH and recited it to him and over the objections of my instructor I performed the flight around the patch, left the gear down and noted that the left fuel cap was leaking!
After that experience I knew all I ever wanted to own was a Mooney - strong, fast, sexy and efficient!
