If you stay in mid air, will the earth rotate under you? does it mean that if you stay in one place in mid air for a long period of time you will be traveling.

The air rotates along with the earth.

No, this is completely wrong. First, there is air resistance that would drag you along, but even if this weren't the case - if there were no atmosphere, if you went up in the air, you still started off with an initial velocity, because you were on the surface of the earth, rotating at enormous speed. Thereafter you would continue to accelerate in the direction of the center of the earth (since you're adjusting your distance relative to the center to maintain your altitude with the helicopter), meaning that your relative location wouldn't change at all.
I'll leave it as an exercise for the reader how your helicopter stays aloft in my hypothetical no-atmosphere example...

Assuming no wind/friction, it is not on the different fringe of the globe. The helicopter has an angular speed (rotational speed) that would not purely disappear. That speed continues to be consistent. it is going to land precisely the place it took off from. EDIT: the two human beings under me are incorrect. the factor is the angular speed continues to be a similar. very like in case you bounce mutually as on a airplane. you will no longer today provide up and slam into the back wall of the airplane, you will nevertheless return and forth on a similar horizontal speed. purely considering you're no longer rapidly linked to the airplane once you bounce does no longer recommend you provide up. PPS: hispanicpanic, it extremely is shifting with the Earth. Assuming we are brushing aside air resistance, it does no longer lose that speed. the place did the fee bypass if it lost it? Momentum must be conserved.

Oh, come on. Really!
Planes and helicopters both use force against the air to fly and move forward. If the air is not rushing past (Except due to wind, which is a weather phenomenon), why would the helicopter move along?
Anyway, if the Earth is moving 700 mph (which is about 1200 feet per second) where most of us live, by your scenario, we would only have to jump in the air and we would land hundreds of feet somewhere else.
You are just not thinking, my friend.
Anyway, to put is simply, all objects on Earth, including air and helicopters, are gravitationally part of the Earth.

It's true as another poster said that the atmosphere rotates along with the earth. Of course, if you were staying "motionless" with respect to the sun, you'd end up somewhere in outer space because the earth would have moved away from its previous position.
Einstein points out to us that there is no such notion as a fixed position in absolute terms -- only relative to other objects. And your question ultimately depends on some notion of motionlessness.

the atmosphere rotates with the Earth so this wouldn't work at all.
for it to work you'd have to get out of the atmosphere - which a chopper couldn't do, since it needs air.
people use a lot of machines high up above the atmosphere to "hover" above while the Earth rotates. These are called satellites.

The atmosphere rotates with the earth so you would not land some place different.
If you stand, sit or hover you are travelling through time and space.

In practice helicopter pilots position their aircraft to a land bearing so that they will actually remain over the same peace of land regardless of the earths rotation.

Yes you are right.

No, I am sorry. I was wrong in my previous answer. I did some research and found that the atmosphere moves with the earth, due to the magnetics and the gravitational pull. I am sorry to have mislead.

No, you won't, because Earth's gravity holds you in place. It is difficult to overcome it. You must reach escape velocity to overcome gravity. Rockets can do it, but helicopters cannot.
