Why doesn’t it spin independently of me and I end up in another country or something? And if a spaceship watched earth from afar, at one point would it start spinning with earth and at what point can it observe the rotations of earth without being part of it?
In: Planetary Science
Because the helicopter is held up by the air and the air is moving along with the surface of the Earth.
A spaceship could conceivably stay “stationary” above the Earth as it rotates, but that would require constant thrust, and it would quickly run out of fuel. Real spaceships stay up by [orbiting around the Earth.](https://what-if.xkcd.com/58/)
