I unbuckled my seatbelt and opened the door and was standing outside when I said: “Glen, fly it around the pattern once by yourself and after you land come back here and talk to me. I’ll be standing here waiting for you. Enjoy your flight.” I had seen the painful expression on students’ faces at just this time before, but Glen’s expression was particularly bad.
This particular day Al was flying on his third hour of supervised solo, meaning these solo flights needed to be approved by me beforehand. Perhaps 20 minutes after his takeoff, Al called on the Unicom frequency: “Bob, I’ve got trouble with the controls.” I responded quickly. “What’s the trouble, Al?”“I can’t move the control wheel forward or back. It’s stuck a little aft of the neutral position.”
