I was at the field Tuesday, and some guy had been doing laps with his engine powered high wing trainer style plane for at least 15 minutes that I am aware of (I taxied out, flew, taxied back all the while he was in the air) and then back in the pits I hear guys yelling, saying "hey where does he think he is going?" and so on. Turns out the old guy lost sight of his plane, and it motored over the golf course. He just started walking back to the pits like he gave up and guys started yelling at him, telling him where his plane was and then shouting "hey pull up now", "turn left a bit" "pull up" etc. I don't know if he ever figured out what the heck he was doing but the plane spiraled in onto the golf course. I sure hope it did not hit anyone. The old guy just left, didn't say a word to anyone...
