I know speed is very hard to guage without something to refer to other than clouds, but it is pretty amazing that that aircraft can maintain controled flight at virtually zero airspeed over the lifting and control surfaces.
Any idea what the plane weighs during the demonstration??
I cannot see any vectored exhaust like a Harrier has, is hot air directed over the wing or control surfaces to aid in lift or control?? I can see the computers 'working' the control surfaces, and I'm assuming the thrust as well. but non-the-less:
VERY amazing... But,,, can it carry 150 customers???
