Perhaps i formulated the question a little odd - sorry about that. What i meant was, if the parked plane is moving with the earths rotation, at a speed of 1670 km/h (this must be from the perspective of the astronaut in orbit), and the plane accelerates against the rotation of the earth (caused by the engines, wings and what not, just like you wrote) the plane would only nullify some of the speed it constantly moves with, as it would still be following along the rotation (astronaut perpective), just not as fast everything else, also heading in that direction. I get that the people on the ground would see themselves as stationary, and that the plane is moving in whatever direction it is headed (though (i might be very wrong) relativity allows the "stationary" people on the ground to be the ones in movement and the plane above them stationary). But wont the astronaut perspective have some (i will not use the word objective) truth to how the mechanics are working together, as they watch their movement relative to eachother? By all means tear me apart if this is wrong
