As the earth rotates 15 degrees in one hour west to east, suppose a plane remains stationary in space & then after one hour the point of earth coming below it will be the place which was 15 degrees to the west than when it started in stationary position ?
Is this possible (if we think that a plane can remain stationary)?

This is theoretically possible, but easiest at higher latitudes (because the speed required is less). Since all motion is relative, the plane is stationary with respect to the Sun and center of the Earth, but not with respect to the Earth's surface.

If it remais geostationary, as some artificcial satellites do, it will be always on the same meridian. But if by stationary you mean with respect to the stars, then the answer is yes, it will go west at 15 degrees/hour.
To remain stationary in the sense that you mean the airplane must fly to the west at a speed to cross 15 degrees by hour. It is possible for actual airplanes to do so. If you are at equator you need a supersonic airplane (1,670 km/hour), but going to a north latitude, you can do so even by bycicle.
I apologize for my bad english, but I hope I made me understood.

It's pretty tricky - apart from the friction acting on the plane by the atmosphere, meaning that it will - in effect - have to use it's engines to work against them. Added to that, you will need to have a reference point that is not on the earth - a satellite or something, to ensure that the plane's position in space is unchanged.

I can imagine it happening, and you would be 15 degrees further west, but this begs the question - if it is so difficult, why do it?
