One time I was taking said GF for her first general aviation flight. We were taxiing out when we notice the 206 that had just taken off was turning back towards the field.....she said "what's he doing?" I said....."Um.....crashing". Because by that time the 206 had done a 180 but was now about 300-400 ft away from the centerline in a 70 degree bank and 70 degree pitch down...it came down right on top of a 310 and a Bonanza. No fire or anything but it was really bad to watch. We decided that maybe we'd fly another day. Three planes totaled. I later learned the 206 pilot only received a gash to his forehead and it was the 'ol water in the tanks. GF did fly with me many other times though.
