Can a Plane on a Treadmill Take Off?

Taken to the extreme, it might be considered ambiguous but that is only
nit-picking the puzzle. The general answer to the riddle is: if the plane
has enough excess thrust to overcome the additional drag of friction of the
wheels turning at twice the liftoff speed, the plane will fly. It will
accelerate slower and require a longer run due to the excess friction, but
it will fly.

Taxi is just nomenclature for the airplane moving along the ground.
"Takeoff run" would be more correct I guess, but in this case things
are so weird, as it is ambiguous whether the plane is going to takeoff
or not.
