To generate the life necessary for takeoff the 747 needs an airspeed of 180mph (fully laden cargo & fuel). It generates that lift by having the engines push what they're attached to (the plane) until there is sufficient pressure differential between upper and lower edges of wings to lift the swine skywards.

Unless there's some deeply serious or humorous twist to your teaser, it ain't going anywhere if the conveyor speed is perfectly matched to the relative ground speed generated by the engines. Until it runs out of fuel that is - at which point it will begionn to move somewhat differently....
Congratulations - you managed to make a completely incorrect answer look vaguely intelligent.

Skill Leverage started this thread Bramble let me ask you this; if a plane's wheels stop spinning when it's in the sky, does it crash?

Instead of the engines pushing the plane through the air, they are pulling the air over the wings. Quid pro quo.

(Note, I answered before I thought about it and am one of the imbeciles that got it wrong).

it's worth pointing out here that it can't work in theory as the conveyer belt would have to move at an infinite speed...

Plane will remain stationary.
Isn't moving relative to the air.
That's it.
