HAY /sci/, logic problem!

There is a giant, 10 mile long stetch of runway with a 747 on the middle of it. The runway, however, is specially designed to move, much in the same way that a treadmill will move, in the opposite direction of the plane. Secondly, the treadmill is attached to a computer which will match the acceleration of the plane exactly and constantly, in the opposite direction.

What is the result of this experiment? Does the plane ever take off?

Lift is generated by air resistance against the wings. If the plane isn't moving there's no (well, negligible) air resistance and thus negligible lift.

"in the direction perpendicular to the relative wind."

RELATIVE WIND.
