devs, no matter how powerful the treadmill, there is no way it can stop the plane taking off. Ever.

devs... sorry for being so ignorant, but can you explain to a relative moron like myself exactly how you plan to keep an aircraft stationary by just using a rolling treadmill?
MT misses my point entirely. Scenario 3 which I pasted directly from a website that explains the whole thing would only be attempted by an idiot because of the reason you are trying to point out. The treadmill would need to be "powerful" to start the whole thing moving in the first place.
FN Are you taking the piss? Are we still in frictionless wonder land or the real world? In frictionless wonderworld the ac will stay still on a treadmill. In real world you would have to use enough forward thrust to counter the friction of bearing and weight on wheels on ground.
Any more thrust would give forward motion relative to the ground and air and lift would be produced.
What about if a helicopter is weighed in a box and then takes off and hovers. It's still inside the enclosed box so does the box weigh the same?
