No, Professor Redekopp is not waving, "Goodbye," to the glider. Until about 0.1 sec. before, he had been steadying the glider's left wing as it waited to be lauched. On the far side of the laucher, from the left, are Aaa, Bbb, Ccc, Dylan Fincham, Dr. Adam Fincham (Dylan's father), Andreas Figueroa (on the ladder), Ddd, and Eee.
