A helicopter can stay in the air for much time then why should we pay for the flights frm one country to another, the earth will rotate(after 24 hours) and the other country will be under the helicopter and we can land their?If it seems to be funny then it can be bcoz iwas also asked this question by someone and i could not answer it.

Simple Answer
Earth rotates with its Atmosphere
(This question was asked by those who criticized Aryabhata, when he stated in his famous work Aryabhateeya (AD 499)that Earth rotates about its axis. The only difference in question was that "a bird" instead of " helicopter".)
The Indian texts call the phenomina as "PRAVAHA VAYU". -Flowing Wind. That means the air & helicopter are also spinning in the same speed as earth so that there is no distance lag between the two.

Objects in the air are rotating along with the Earth and at the same speed. The world is rotating at about 1000 miles an hour so if your theory were valid then the clouds would be passing overhead at that speed. A helicopter that is just hovering in one spot is acting like a geo-synchronous orbiting satellite in space.

LOL you're assuming that when the helicopter rises, the earth rotates under it. The earth rotates WITH the helicopter! Have you ever heard of gravity? Same goes for aircraft. They all rotate with the earth, at the same speed. (The reason why westbound flights take longer is due to the jet stream; it has nothing to do with rotation).

The ~ 1000miles per hour the earth rotates also has the helo starting out at the same speed and direction. Remove the air (I know the helo won't fly without it!), remove the gravatational attraction of the earth towards the helo, stop the forward momentum (the original 1000MPH). The helo will now sit still while the earth rushes by. Same reason a fly can go 101 MPH inside a train that is moving 100MPH. The environment that the fly is in moves him with it,

that's coasting continuously in the frictionless vacuum of area on the momentum it have been given whilst it grew to become into formed billions of years in the past. there is not any power source. None is mandatory for the reason that there is not any friction to sluggish it down. (certainly, there's a small quantity of friction due the the Moon and the tides, and that slows Earth's rotation via an particularly, VERY small fraction of a 2nd each and each 300 and sixty 5 days.)

DUDE! You've got to be kidding me. This question doesn't take into account anything in real life. Think about this for a little while, if you can't begin to see some flaws in your plan....
I'll get you started, if you hover in the air for 24 hours (somehow magically, there is no weather, and your helicopter never runs out of gas, which is somehow free for your magic helicopter, you don't run into mountains, buildings, trees, etc.) so if somehow you magically hover for 24 hours you'll be in the same place you started.

this wouldn't work, because gravity keeps your helicopter and all the air surrounding it in the same location.
it would work if the earth would not rotate, and would start rotating once you left the ground. But unfortunatly the whole planet and your helicopter are already moving. So if you leave the ground you do not instantly stop following this intertial moment you already had prior taking off.

No, the helicopter will be affected by the Earth's gravity and thus will rotate with the Earth.

You see since gravity is holding everything in place then a helicopter floating is only using enough force to hold it off the ground so its going to stay in place other than winds blowing against it - so in other words gravity is holding the helicopter in place.

Because the air spins with the earth. If it didn't, the wind would be blowing at something like 700 MPH at the equator.
(actually, the wind would be still, but that's how fast the earth spins. If you were standing there, in this case, it would be exactly like riding on the OUTSIDE of a jet airplane that was exceeding the speed of sound.
