I was thinking about flying my P3P under a bridge. The bridge is a massive steel structure that would be about 40' above my P3. I only have about 30 flights under my belt and all flown in wide open spaces. Is it possible that my P3 could loose its gps bearing while under the bridge and at the same time lose contact with the RC because of interference. In that case it would attempt to land from where it lost contact, straight down to the river flowing under the bridge. Would experienced flyers skip this flight as too risky?
