On May 24, 1963 I was cleared for a one-hour flight out of the traffic pattern. I had been accepted to start at the United States Air Force Academy in another month, and this would be my last flight at Lovett Field. I was really looking forward to this flight after finishing my afternoon classes at the University of Delaware. I mean, I was REALLY looking forward to this flight. You see, it was a very warm spring day, and the word at the university was that the coeds would sunbathe au naturale on the roof of the Student Union building (the stairs to the roof had a sign that read "Women Only"). I wanted to see for myself if this was true! Waldo probably figured I had an ulterior motive when I told him I wanted to check out the route from the university to the airfield. Before I took off he said, "Be sure to stay high enough that no one can read the airplane numbers". So I flew at about 4000 feet over the University of Delaware, looked down at the Student Union building, and discovered that from 4000 feet you can't tell the difference between a lawn chair and a sunbathing coed. So I headed west to practice some airwork. I did a few stalls, practiced some chandelles, and got the feel for the airplane in a variety of maneuvers. And then it occurred to me that I had no earthly idea where I was! My airplane had no electrical system, no radio, no aeronautical charts, and I was totally lost. I made another discovery on that flight. I learned that even though I was still bathed in sunlight, at dusk the ground below is very dark and hard to distinguish landmarks. Fortunately, Waldo had been cutting the grass on the sod runways, and the distinctive runway pattern clearly stood out in the distance, and I was able to make my way back, albeit a bit later than anticipated.
