No need to provide photographic proof Jon there was a reliable witness. I was there and saw it happen, but it wouldn't have worked had the model not been equipped with elevons to provide roll control. And it didn't continue to work as the model was slowed to land and the lift provided by the broad fuselage became less than the weight of the mode! at which point flight ceased when it stopped being an aeroplane and turned into something more akin to a sack of spuds.
