Cracking geek respect folks. I asked and you tried to tell me. thats what i wanted to know. I wanted to know physics. Not if MAry or John would get back together. A great read and i await the answer at the end of it as TDP DOES sort things out

But that isn't implied in the question. The question is worded, in my opinion, in such a way that the thrust from the engines will force the plane forwards, but the forward momentum is transferred, courtesy of the wheels, onto the rolling road therefore providing an equal amount of momentum onto the rolling road.

In real life this obviously won't be the case, but the question, which sounds as though it's been taken from a GCSE physics exam, would presume perfectly balanced forces and counter-forces.

Urgh.

The whole dealiabob about the wheels in the question is a red herring.
