Hey, wait a minute; that only works if the plane achieves its takeoff

correct me if I'm wrong, but) ground speed has nothing to do with takeoff.

I'm not a pilot, but I do know a few. I always thought takeoff speed was a
function of ground speed and wind velocity/direction, and of course weight. How
is it ground speed has nothing to do with takeoff?

I'm not a pilot, but I crashed a hang glider one time. ;-)

What matters is the wind speed seen by the leading edge
of the wing. A plane could become airborne while completely
at rest, relative to the ground, so long as the leading edge
of the wing saw enough wind speed. Think wind tunnel.
