Has no one noticed that other than a few exceptions, those were paratroopers, not hang gliders? There were a few ultralight riders with panoplies and fans, but most were paratroopers dropped from high above.

Hang gliders have to launch from heights and count on favoring winds and currents to stay aloft and are uncertain as to where they land.

Those were paratroopers. Check the video. Who dropped them? Were those Egyptian flags?
So hard to know these days.
