It is not me. I happened on two guys flying their gliders in a field not far from me and was intrigued by the agility of the flights. The ones they were flying were carbon fiber with foam wings which were polyurethaned for strength. The one pictured in this launch sequence has ailerons, flaps, rudder, and elevator which gave him great control in that both guys caught their planes rather than sliding them down on the ground.
I'm impressed by the length of the fuselage!
