# Flight from London - New York is quicker than the way back?

Watch
#1
I was wondering the following:

Since the Earth is rotating from West to East, does that mean that flying from London to New York will take less time than from New York to London?

Why? Why not?

The time depends largely on the wind speed and direction. Generally speaking it is quicker to fly from USA to UK than UK to USA as the prevailing winds are normally West to East across the Atlantic

I forgot to give further details. What if the following conditions are there:

* Wind speed is ignored
* The same plane is flying with the exact same weight
* Same pilots
* Same speed

In other words, the speed will be same both ways. But the Earth would be moving WITH the plane (from NY to London) and AGAINST the plane (London to NY).

Would the Earth's rotation direction affect the time and why?

You might find this interesting.
The flight times can vary drastically if use is made of the jet stream.

But its an unrealistic situation as the wind speed and direction is directly linked to the rotation of the earth.

It takes same time simply because the earth is not spinning... otherwise one flight would be impossible as the earth is supposedly spinning at a 1000 mph and a airplane travel at a speed of 500-600 mph

I hate to point this out, but the thread is more than six years old.

To get you thinking, try relating Newton's laws of motion to the problem. Specifically action and reaction and gravitational acceleration.

Nah, doesn't the Gulf Stream make the return journey like 2 hours shorter?

Very interesting question. The short answer is that yes the Earth spins, but not just the ground.

The atmosphere spins too:

I think you mean the Jetstream. The Gulf Stream is an ocean current (and the name of an aircraft manufacturer).

Yes, the Jetstream is a vortex high in the atmosphere, caused by the meeting of the polar and sub-tropical air masses and the Coriolis force induced by the earths rotation.

It does indeed flow west to east at up to 200 mph (when conditions are favourable) and can reduce flying time across the Atlantic from west to east by up to 2 hours.

Lol yeah I meant the Jet Stream. This is why I'm not a scientist

The atmosphere spins too:

Just like the air (atmosphere) in a moving vehicle (plane, train, etc) is moving along within the closed system (moving vehicle) but if you throw a coin in the air vertically, it will not fall next to you... the coin should fall vertically but will be further back to you because of the moving vehicle.
Same with a plane in the air, if the earth was spinning the one trip would be impossible because of speed, and the other should take less than 6:00 very much less
