Thanks. I mean I don't mind derailing threads when its a connected subject a bit but some people are touchy about it. We aren't fully on the same page but close enough.Even powerful aircraft are not immune to stalls. What a stall actually is: the airflow detaches from the airfoil. There are several scenarios in which this can occur. First is insufficient speed, which is the one that is easy to understand. Second is changing course too aggressively (high-speed stalls). Third would be a catastrophic disruption in the air itself, the best example by far is the updraft of a storm.
The same physical phenomenon is happening. The airflow is obstructed, and the aircraft falls out of the sky.
More info so as not to derail the thread too far: https://wikiless.org/wiki/Angle_of_attack
If I understand what you are asking, no, that would violate the second law of thermodynamics. But there are scenarios in which you could create that illusion. Gliders come close, but they are using updrafts and air currents to generate lift, which are influenced by the sun, so the energy is coming from somewhere else.
Here's an interesting video I found on the subject inbetween your replies if you want to poke about the subject yourself a bit.
