The treadmill in NO way can counteract the THRUST of the engines.
correct, that's not what i was saying and i'm acknowledging this is a departure from the original question. the followup question involves whether or not a treadmill could be designed to match the FORCE (or acceleration) of the plane. in which case, wouldn't the answer be yes?
