A plane is standing on a runway that can move (some sort of band conveyer like a treadmill). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in opposite direction).
The question is: Will the plane take off or not? Will it be able to run up and take off?

Oh Jesus not this again....the answer is no, because at the takeoff speed of 175mph the air moving under the wings aids the air produced by the jets.

Wrong. It doesn't matter what the wheels do. The wheels could be spinning at 1000 mph and it doesn't matter. The thrust of the engine will push it forward. Now if you have a 10,000 foot conveyor, the plane will take off.

Its the combination of the thrust of the engine (jets moving air which goes over the wings) and the air velocity at 175mph (air moving over the wings) COMBINED that moves the plane. Yes if the engine jets were big enough, the plane would move w/o the air velocity of the moving plane. Its like how do you turn a bike fast. You do A PLUS B. Countersteer and lean. Can you still turn w/o leaning? Yes, but is takes much more force.

But again the real question is if the rolling equipment will be able to withstand the conveyor belt at 350 mph? Because if it fails, that plane is gonna burn in a firey crash

![]() I don't have the slightest clue what you're trying to say.... But the plane doesn't give a f**k about thrust, all it needs is air moving across the wings. If the plane is sitting still and there is a 175 mph headwind, it will lift up and take off. Engines don't move any air across the wings, all they do it push it forward No, they don't

I'm sure if you reached the 175mph and stopped the engines the plane wouldn't lift. You would have to increase speed. But yes air moving across the wings is the only thing lifting the plane, but we are discussing where that air is coming from.
