Crestline Soaring Society

I'd classify it as prank. Other videos from same website displayed
models losing wings in similar aerobatics and R/C pilots were
able to land them with only one wing. The wing in this video separated exactly the same as models. Don't believe real wing would
break in this fashion without displaying alot more damage to the remainder of the aircraft. No cables or hydraulics hanging loose.
I'd say this was a spoof.

I didnt see the guy get out at the end until later. It looks like its rc by the twitchiness of the roll and bounce of landing.

Was there ever really any question? It was a fun vid to watch but I was expecting to see Gumby climb out of the cockpit - there was something very clay-mation about it....
