While at Butler University(CTD) I received ten hours of instructional flight time in a J-3(cub). We flew out of Hoosier Airport which had no runways just open field. Our instructors were civilian pilots. We had the same instructor for nine hours and a check pilot on the tenth. On the first hour he had me trying to fly a rectangular pattern. The second hour he said "cadet, do you think you can take off ?" I used up a good portion of that field but did get it in the air. At the end of the hour he said "you got us up here can you get us back on the ground". I can still here him yelling ya-hoo as we bounced along. What an experience for one who had only sampled flight on a fifteen minute ride at the Missouri State Fair. The next seven hours were routine training (spins etc.). Then came the final tenth check ride. We took off and he put me through the various maneuvers and landed. I passed with this comment in my log book "Cadet Runnels gets the airplane to do what he wants but I am not sure how he does it"
