Coodakid3 had the engine fail on his third lesson (in a Drifter) necessitating a landing on a gravel road. Then had to sit and watch while I had to deal with an unforecast 40kt gust that tried to encourage our Jabiru to perform a slow roll while still on the takeoff run. Then had the rudder lock hard over at 3,000ft in his CT4. The instructor side slipped into a wheat field and the local newspaper. The PC9 gave him two RTB's with a possible canopy unlock and failed fuel system. And the Hawk 127 gave him a total nav system failure on a moonless night.
Possibly no coincidence that the Air Force then sent him off to single seat fighters.
