If a helicopter is on a giant rotating disc that spins the same speed in the oppisite direction of the rotors. Will the helicopter take off?

Here we go again...

I would think the blades would remain stationary and the chassis would rotate so no.

If a plane is coming in for a landing on a treadmill where the treadmill is going in the opposite direction of the plane, what happens when the plane touches down?

A tree falls on the originator of the airplane on a treadmill question in the forest. Do we rejoice?

If a fat guy is running on a treadmill on his private airplane when they try to take off, does the sudden forward thrust of the plane make him fall off the treadmill?

blades are statutory in respect to the air = zero lift

It depends on the type of helicopter. Some, including most Kamov designs, will take off.

considering the "giant rotating disc" would have to be spinning in two different directions at the same time?
