mythbusters have confirmed it, it takes off.

Common sense and basic physics confirmed it a long time ago.
I'm amazed at the amount of people in here that think it would stay still. |

I am perfectly happy to accept that it would take off, but I don't understand why.
I don't know physics, all I do know is that a plane generates lift by using it's engines to propel itself forward, moving air over the wings and letting them do their thing.
If the plane is on a hypothetical (moves-instantly-counteracting-forward-motion-of-the-plane) treadmill, I can't get it out of my head that the contact with the treadmill would stop it moving forwards, preventing air from moving over the wings and thus preventing lift from being generated.
The relationship of the wheels to power to friction don't mean a jot to me, they are just the contact with the ground but it is that contact with the treadmill that I keep thinking stops it from moving forwards.
Why would the plane lift off if no air moved over the wings because there is no forward movement.
I am genuinely interested why - I'm sure this will come up in a pub sometime.
Cheers for your help in helping me understand.

This is really an odd thread.
As was said way earlier - the treadmill is irrelevant.
An Aircraft moves forward in relationship to the AIR moving through it's thrust mechanism, prop, jet, anti-mater reactor - whatever. The wheels are there simply to keep the fuselage from dragging along the ground.
It makes ZERO difference whether the rocket/aircraft/minmatar shuttle is on a tread mill or not.
It's thrust will move it forward compared to the space around it - not the ground. The ground is only relevant if it supplies enough friction to the body of the aircraft to keep it from moving forward - which is why aircraft have wheels.
The only problem with a Minmitar Shuttle taking off - is that I've seen no evidence that it does have wheels. I have seen evidence however that it can simply hover over it's docking station pad - which means it wouldn't need wheels anyway.
...
It should be interesting to see how many more times people have to say the same thing before they stop getting an argument ... or ... how long it takes for the trolls to get tired of this thread ...

You just told us why, though. The ground does not stop the plane from moving because a plane doesnt use the ground to move. It uses the air.
