"There is a minimum requirement for flight which
it met. That involves maintaining altitude and
speed over a certain period of time, whereas in
a glide you either lose speed to maintain altitude
until stall or lose altitude to maintain speed until ground.
The flyer maintained and even appeared to gain
altitude after the pull cord was released from the car
and maintained speed throughout the flight. If you are
wondering how I get this from the video, it's because
I am familiar with the researchers who did this."
A good glider can easily do dozens of meters while losing only one meter in height(I flew one), so it is impossible to tell from the shaky video. But if he knows those guys and tells the truth, awesome!
