A plane on a treadmill *does* take off. There was even a whole thing about it on Mythbusters a while back.
They tested it with a model plane - it took off.
They then constructed a massive "tread mill" like setup, with a real plane/pilot. Despite the fact that the planes own pilot said it wouldn't take off. It did, and he later said that it was basically no different than a regular take off.
Result -> Planes take off without effort. (remember the propeller supplies the power to the plane, not the wheels
)

wrong.. a plane needs wind to take off
If the Sun explodes at night will it do slightly less damage? Wait..isn't the Sun exploding ALL the time anyway? (If it's not actually Electric that is..) if it is Electric would it still explode or just kind of fizzle out?
Did I open two or three cans of worms there?

The sun is continuously exploding.

But it has "wind", as it's still moving forward even if the treadmill is moving backwards equally quickly. The wheels spin backwards at the speed of the treadmill but do not cause the plane to go backwards; they just freewheel.
Which raises the question will a 747 accelerate to 250mph in half a second, maybe someone can employ newtons laws in working that one out
No it doesn't raise that question. Who said that it reaches 250mph in half a second? It's just a normal takeoff. If the treadmill instantaneously reaches a speed of 250mph backwards, do you think the plane must exert enough thrust to also travel forward at 250mph to stay stationary? If so, you're wrong
.Read here where it was already discussed in depth on these very forums, it's now locked for a reason
(because when this discussion starts it neverends)

Congrats... you fail
It was done, twice on different size models, on tv
they even explained it... I suggest people watch the episode (I think it even had a name like can a plane take off on a treadmill) or something

Damnit, you mean a plane at an airport can't take off unless there is at least a slight breeze?

I think he just means air moving over the wind firm either the plane moving or theoretically by an insanely strong and well directed breeze

Oh, well the plane does need moving air doesn't it, or at least air to be moving over the wings like what happens when it moves forward so that it get;s the difference in air pressure above and below the wings?
