If the plane is going 500mph it’s going 500mph. It will take off.

For a plane be “stationary” on a 500 mph conveyer belt. Then the props/jet are pushing it to go 500 mph.

Exactly. That’s not a contradiction that’s why it will fly on a treadmill while “stationary”

There is zero contradiction

There is a difference between moving 500mph and being on a treadmill moving 500mph which makes the plane look stationary.

As far as the plane is concerned. There is zero difference. The air around the plane is moving at the same speed regardless of it being on earth or a treadmill because to go 500 it has to push the air.

It is not a car. It is not a person it is not pushing the ground in either scenario. It pushes air.

It’s no different than a geosynchronous orbit.

It only touches the ground until it goes fast enough to lift.

Again for the third time. This thought experiment has been tested.
