I have been flying at my local club for about three months now. My trainer was the victim of this phenomenon. There is a large metal building about five hundred yards away from the runway. I got close to the building at a low altitude and lost all controls. It did a nose dive into the yard of this building and hit a stack of I beams. Totaled. Since then I have seen two more fall out of the sky near this building. They weren't mine as I stay very clear of it. Most of the people at the field claim that the receiver in the plane begins to get two singals from the transmitter. One that is being sent and one that has bounced off of the building and then is received. Has anyone heard of anything like this? A couple of old timers can count many planes lost near the building and consider it a sort of Bermuda Triangle area and warn people to stay away.
