When people think they know what they're talking about, but actually, they don't.

Effect of wind on airplane / aircraft flying (head / tail / cross/ gust) (7 min 1 sec)

Go to 0:11 for the nonsense part.

And you can't tell them they are wrong because of this:

The determining factor here is how long the pilot can continue to fly the aircraft as it's groundspeed takes it out of visual range.

A glider in a steady headwind capable of keeping it aloft, while being controlled in a manner that prevents it from turning downwind or otherwise crashing, can stay aloft until it's receiver battery dies and that control is lost.

It's essentially a kite without a string, and kits don't need motors. They also generally don't have airfoils. All they need is angle-of-attack and a headwind and they can stay there indefinitely.
