So would it be safe to say that a large commercial aircraft flying overhead

overturn vehicles?

Ahem... I was held for takeoff behind a good size passenger jet at
Exeter (I think it was) long ago in a powered g;lider (a Fornier RF4)
When cleared I hit it, and at about 50 feet did a smart involuntary 90
degree roll, and headed straight for the tower. I corrected when I
could, and put it down to vortex interception.

Controllers weren't so careful of it at the time
