Really! And why would that be then?Its a bad question to start with as the conveyor and the aircraft wheels cannot go at the same speed.

A conveyor has a larger circumference so for every rpm of the conveyor, the wheel may do 50, 100 or even a thousand.
How do you control that

read the op and it states they both do the same and yes it will take off i've seen the video evidenceReally! And why would that be then?Its a bad question to start with as the conveyor and the aircraft wheels cannot go at the same speed.

Right, saying as Mr S is, I think, being mischievous with this (its causing argument already!) here's my answer.... the right answer
The wheels of an aircraft 'spin freely'. They DO NOT provide propulsion or forward motion to the aircraft and therefore do not 'push against' the action of the conveyor belt. Any forward motion (thrust), comes from the engines or propellers not the wheels. Forward motion/Thrust therefore is being applied to the aircraft 'body'. It has NOTHING to do with how fast or slow the wheels happen to be 'spinning/free-wheeling'.
According to Newtons Third Law of Motion, every action has an equal and opposite reaction. The thrust of the engines is acting against the 'air'. Because the wheels are free-wheeling the conveyor belt cannot exert any force on the aircraft with respect to forward motion. All that it will do is make the wheels spin faster or slower. There is no force in this scenario that is opposing the thrust vector of the aircraft. Therefore if the conveyor belt cannot exert any force on the aircraft, which it cannot because as we now know, the wheels spin/free-wheel, the aircraft will take off.
Phew!!! I'm off to make a cuppa now. Anyone want one?

Now i'm only showing this pic of myself in order to correct your spellingJust noticed the title.
