A plane would still move without wheels though. (woulnd’t be very safe or comfortable) 
no offense, but i can’t explain this any better. i cannot see how there is even a question in anyones mind about this…
yea, but a plane without wheels on a conveyorbelt that acted in opposition to thrust would have a harder time taking off. This is because now, due to friction, the treadmill is capable of applying an opposing force, thus decreasing net force, thus decreasing acceleration.
lol yea it would take off without wheels casue the belt has nothing to match its speed to thrust is pushing the plane forward.
lol i never thought i would be talking about physics outside of school i like this thread lol
right and i agree, but he was talking about on a regular runway.
it will lift off, but I’d wanna check those wheel bearings afterwards. 
is there an actual answer to this?
Mythbusters
lol we should email them about it and see if they could do it.
There was so much stupidity on the first page of this thread, I don’t even want to post the answer, people wouldn’t listen.
But yes, this was done on OT several months ago, and the stupidity of the majority of the population and the inability to think rationally amazes me. You do not need a physics degree to understand why what would happen would happen.
People that talk about things that aren’t possible, yet are seriously debating a magic treadmill should be shot in the head and take a class in hypothetical thinking.
fuck yeah. someone write it up and send it in, im sure they will consider it. although it isnt a myth it would make for a sick experiment
so, the only way to keep it from taking off is for the wheels to reach a speed where the friction can provide enough force to counteract the thrust.
i had bushings like that in my turbo

This thread says alot about the users posting in it.
FWIW in this scenario the plane will actually liftoff sooner than the same plane on a fixed runway. Why? The treadmill will create a barrier layer of air moving roughly the same speed as the treadmill. This will increase the “wing in ground effect” factor. This effect would be greater than the negligible drag from the gear wheels rotating at double what they would at a relative airspeed.
Uhhhh, are you people serious when you say no?
Edit I really hope the “No” people were kidding.
oooh, yeah, like the steady breeze that you feel standing next to a moving train…
looks like a bunch of poeple already beat us to it though

all i have to say
no forward motion = no lift
planes need lift to fly
thats why they have wings.
the engine can only pull the plane so fast and its not going to magically leap upward with no wind beneath its wings.
thats why helicopters have those things on top.
It will definitely take off. It will just take a bit longer because of the distance canceled by the conveyor belt. So instead of taking off when the wheels are spinning at 160mph (which is totally irrelevant to the operation of the plane), they’ll probably be going closer to 320mph, but the plane will still be going 160mph at take-off.
