I thought his answer was close to correct - I must be a total tard. What is the correct answer Mr. Engineer?
Earth's gravity would not keep in in place any more than Earth's gravity makes the moon keep a geosynchronous orbit. The difference between the moon and satellites and this helicopter is that the moon and satellites are orbiting the Earth while the helicopter is not. The mechanism that keeps them from crashing to Earth is totally different.
What you're asking is if a helicopter could hover in the air at a fixed point relative to the center of the Earth as the Earth spins beneath it.
All of the stupid responses to this question are either from people who have no idea what they're talking about, or from people who know what you're trying to ask but are mocking you for not knowing how to ask it.
To answer your question: could a helicopter do this? Sure. Unfortunately, its not as simple as climbing to a certain altitude and putting it in hover mode. A bunch of differenct forces will be acting on it that the pilot will have to correct for.
