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?

ELI5 really : you look at a fish in a fish tank on the ground. The fish tank moves with the ground and you expect the fish to move with the fish tank right? You don’t think the window will slam the fish in the face as the tank move with the earth spin but the fish would be still and move through water.
Well, your helicopter is the fish and it is the exact same story because air is exactly like water. Sure it is less dense and we can’t see it. But your fish in water and your helicopter in the air will move with the fluid around them similarly. Think of an helicopter as floating mid air.
