RC Plane Experiment

A plane is standing on runway that can move (some sort of band conveyer). 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?

Yep, it's another one of those "Will the plane take off" scenarios, but this time it is a helicopter.

The helicopter is sitting on a turn table that has incredibly sensitive sensors on it. The sensors are there to detect the slightest attempt of the rotors trying to turn. There is no wind. The nose of the helicopter is facing north.

In this problem... the turntable spins anti-clockwise at the exact same speed as the rotor on the helicopter spins. The rotor on the helicopter goes in a clockwise direction. As soon as the rotors move, the turntable matches them. The turntable and the rotors are ALWAYS matched. Neither can go faster than the other. This part of the question has two parts...please answer both. Will the helicopter take off given the above conditions?

dude everyone on here is such an idiot here including you... first, semi-contradicted urself in ur comment. "air isnt moving relative to the ground, so probably the blades arent moving relative to the air either." that's one of the stupidest things ive ever read on youtube. if the air ISNT moving relative to the ground, that means that the "still" blades in the picture ARE moving relative to the AIR. god this is exactly like the mythbusters plane on a treadmill...
