Flying and the jet stream?

I thought part of it was also flying with/against the rotation of the Earth.

This doesn't matter at all. It's all about relative motion. Think of it like this. At the equator, before takeoff, the air, the plane, and the ground would all intially be traveling roughly 1000mph in the direction of the rotation.

You might be thinking of how space shuttles take off in the same direction as the Earth's rotation to give them a little boost. The shuttle's final velocity has to be about 17,000 mph to escape the Earth's gravitional pull, but in this case, that velocity is only relative to the Earth's center, not the ground or air from which it took off from.

The atmosphere moves with the earth. That's why when you jump up in the air, you don't suddenly get slammed into a wall at 10,000 mph.

No it's not. The reason you don't get slammed into a wall is because you are moving the same speed as the earth is and continue to move that speed when you are in the air. Atmosphere has nothing to do with it.

Well, if the atmosphere weren't moving with the Earth's rotation, you woulnd't even have to jump to get slammed into a wall by the wind, if the wall were somehow to stand up to a thousand mph wind as well. Assuming you are in a protective shelter from the wind, yeah, like hawk said, it wouldn't make a difference.

Last night I had dinner with an astronaut. He recently came back from six months on the space station. He's going to Japan soon and the trip will take something like 14 or 17 hours. When he was in space, he said they'd orbit the whole earth in about 90 minutes so the Houston-Japan trip would be like 40 minutes. Anyway, I mainly just wanted to post that I had dinner with an astronaut, 'cuz that's cool.

You're right, of course, but I was just trying to make a point.

I should have said, "Did you ever notice the lack of constant 10,000 mile per hour winds?"

My trip to Taipei a few years ago took a lot longer coming back to LAX than the trip out. Jet Steam. Not much more info but I wanted to get in that I am a world traveler and thus one up El Diablo and his fetish for astronauts. Cuz that's Cool.

Plus I zipped over the international date line, even more cool.

dinner with an asstronaut? sounds kinda gay.

Some more interesting information that everyone should know about Coriolis Effect

Important in the distribution and direction of wind currents at certain laditudes.

Even Ray Zee did not know about this.

About a half dozen times I've flown from Sydney to San Francisco. Each time I arrived before I took off. I laugh at 40 minutes.

yeah, that would make basketball nearly impossible.
