think about this...

[Slow Play Ray]

There is a plane (Boeing 777, prop plane, whatever) on a moving, conveyor-type runway. The runway moves in the opposite direction of the plane at the exact same speed as the plane's wheels. There is no wind. Can the plane take off?

[crunchy1]

What kind of plane?

[noggindoc]

depends...is the pilot stoned?

[MelK]

If there is no wind speed, there is no lift. OTOH, you could be facing a strong headwind. Insufficient data to answer your question.

Airspeed = 0 the plane cannot take off. This would be the same if the plane had a tail wind that was = to it's forward motion.

[NutCrackerr]

No

Good answer, but just seconds too slow. [img]/images/graemlins/grin.gif[/img]

edit:
I see Ray has altered the OP to provide some of the lacking information. My "insufficient information" answer was clearly the correct one. [img]/images/graemlins/wink.gif[/img]
