The 7,274 was the speed in km/h
The method AdHoc used was for a sidereal orbit, which is literally the time taken to fly through an angular distance of 2 pi radians. To reach the same position over the Earth's surface again, a synodic orbit, you would need to account for the rotation of Earth and you would need to work out how far the plane would need to travel before it has a phase difference of 2 pi radians with Earth.
The round form of the earth is kinda like a differential, considering rotation speeds at different points.
Or 2 hours half-sleep are not enough for me... xD
Earth does not undergo differential rotation. Its linear rotational speed does vary depending on your latitude, but its angular speed is constant. Differential rotation happens in fluids.
In actual fact, what am I talking about? Earth's rotation is irrelevant here! The example I gave above was from a purely mechanical point of view, assuming both bodies were being observed from an external frame of reference and the plane was moving completely independently of Earth. It's not, the plane is taking off from Earth, and so to the plane Earth might as well not be moving. The speed of the plane is relative to Earth, so the time for it to circumnavigate is simply what AdHoc said. Earth's rotation doesn't even enter into it.
Huh, oh I was just "Ontopic" with a "random thought"
That's just the teacher in me jumping out
And for me just the petrolhead. ^^
All I did was driven by the intention to convince her being with me.
Now I do it just to make her happy.

Well I hope you're not too deeply in love, because it might hurt a lot more soon.

Oh, erm...well...!?
Just trying to interpret what you write
Then you should write this
"Hope it won't hurt a lot more soon, because you're deeply in love"
Fingers crossed
Uh, thanks, I guess
Why do people make things like this, the internet has ruined my favourite gaming character >.<
i discoverd that im on google street view twice
I'm thinking how Alien is going to be amazing with Neill Blomkamp at the helm

Ok, here's a though... wormholes?
I did a bunch of amateur research (I'm no wizard of smart afterall) and I came to the conclusion they are ENTIRELY POSSIBLE because my keys keep winding up on opposite sides of my apartment from where I left them the night before. But seriously, time distortion has been proven to some degree by communication perception differences from ground control to a shuttle in lunar orbit (or even while still in Earth's atmosphere). That is to say that astronauts "age" at a different rate than us here on the ground or at least would in a controlled experiment. Can't remember the source I saw it from, I just remember it as non-conclusive evidence that wormholes are some sort of super condensed time space field where gravity has a different effect on time-space and perception of time dilation.
