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. biggrin.gif

The rope theory is not relevant in this argument as you are using a 'fixed' point to provide you with the ability to create motion.

If you had a conveyor, started it, and then started the plane engines to compensate this backward movement, surley the opposite would apply, in that if the plane started to progress down the runway, an increase in the speed of the conveyor belt would negate this?
