Just to be clear 'stall' in this context means the wings aren't producing lift any more. It also makes the control surfaces far less effective. You can see a change in direction if one wing stalls before the other.
It doesn't turn the plane into a glider. The video really doesn't make it look like the pilot had much say in where he was going.
Thanks and understood.
That's what I was getting at, an argument against acme possible theory. Just because the plane moved to the left, doesn't mean the pilot had control over it.
