Well the fact remains in un controlled air space some guys fly as low as they want to. Five hundred feet Is the norm but several guys don't follow the rules. I live on an Private airport south end two thousand four hundred foot by two hundred foot wide runway. It's an ease meant so we all own to the center of the runway. One acre lots. I fly in southerly winds only so aircraft are taking off on the south runway. My lot 15 is located about three hundred feet from the end of runway 17. Trees and power lines at the south end of at least one hundred feet tall. Our field elevation is 635 foot above sea level. So the standard pattern altitude is 1,635 feet. If they are using the pattern. Many don't, they fly straight in. Not in the pattern. When I fly my UC I place three red pennants on my windsock pole. All the guys at the airport know what that means. But transit planes don't know that. I fly with a spotter. Wish We had a circle, but we don't so you make the best of it, build and fly. Average flight is about three minutes. AJ I am thinking about another incident at a Airport in the DFW area. I recall reading about it, when I was in the Brazos buzzards. Our news letter. A model hit a Cessna 150 snagged the control lines and lucky the handle was not teathered to the guys wrist. The model hit the plane prop which forced an off field landing. The pilot did not set his altimeter prior to take off. Realised it and set the altimeter after Take off. He was to low and was lost. This happened year's ago. But I recall the very unfortunate incident.
