Here's one- My flying buddy, Tommy Mansur, had been about one minute into his flight when an Army Apache helicopter tries landing in the flight circle, but heli-pilot realizes too late that somebody is flying in "his airspace", so he holds the chopper hovering at about a (7) foot altitude with the cockpit of heli at the edge of the circle and the rotors intruding completely into circle the span of the rotors! Tommy was able to keep his cool and flew all remaining laps over the top of the rotors while we tried to communicte with chopper personnel to keep the chopper where it was at, which they were anyway. When the engine finally quit Tommy dove for the ground immediately to avoid the rotors and made a hot but smooth landing. He thought about walking the plane away from the chopper while he was flying, but was afraid he might trip in the tall grass in the inner circle. When he landed the airman rose out of hovering and landed in the field next to our circle. They said they thought just a man was standing in the middle of their landing area and assumed he would move as they got closer, didn't realize he was flying a plane in a circle until it was too late.
Yawl might ask " What was a real chopper doing landing at our city park C/L flying field?" Well they had taken it over following the Hurricane Katrina disaster. This incident occurred about (1) month after the disaster- we thought the field was back under park control, because of what one official told us. In truth, our circles never were put off limits to fliers, we knew the Air Guard were using the circles so we stayed away for a month and heard from one park person it was ok to use.
