Dragging up the past a bit - TV show Mythbusters ran it's much anticipated episode with a practical experiment version of this question on it a couple of nights ago over in the US.
I don't know when it will come on over here but for the curious Kottke liveblogged it and also links to another good explanation from a guy with a Sc.D. in Nuclear Science and Engineering (whatever that is). And for the hard of attention and understanding - yes of course it takes off.  -------------------- "We are number one, all others are number two or lower!" - The Sphinx, Mystery Men

Ok - as long as you didn't think we meant it suddenly leapt into the air from a stationary (relative to a static observer) start!
I've read back over your reply and this is the key bit: QUOTE ... the tread mill would counter the speed, thus leaving the plane stationary That would be true if the forward propulsion of the plane was through the wheels, but it isn't! -------------------- "We are number one, all others are number two or lower!" - The Sphinx, Mystery Men
