Let say I live in equator. I have an aircraft which can fly stationary 24hrs non stop. At 7 AM in the morning I flew my aircraft off my back yard to some altitude off the ground, and I keept it in stationary. Considering the Earth is spinning, where would I be 12 hours later? Still floating around my backyard (why? I was in the sky, and the earth's spinning!) or I am already floating in the sky of half part of the globe?

Presuming you mean a helicopter with unlimited fuel, then you would still be above your back yard however you would be in a different point in space as the earth has rotated 180 degrees. If you had come out of the atmosphere above your backyard then you would be on the opposite side of the planet from your house.
unless you come out of the earths atmosphere you will spin at the same speed as the earth and will not notice.

The earth spins around an axis.
Earth spins implies all air and all objects above earth also spins along with earth.
The radius of the earth at equator is 6378.2 km.
Its speed on the equator is 465m/s (1674 km/hour) from West to East.
For small altitudes from the surface of earth the speed remains almost same.
If the altitude is equal to the radius of the earth, the speed is double; 930 m/s.
Any object moves along with earth from West to East with the speed pertaining to that altitude.
In other words, all objects whether they are on the surface of earth or in any other altitude in air, rotates about the axis of earth from west to east with a period of 23.93 hours.
Since you have started about 7 A.M, let us suppose the sun rises in east at that time.
Since both you and your back yard move toward east, after 12 hours both will see the setting sun in the west and you will be still seeing your back yard beneath you.

The earth and the atmosphere both move relative to the sun and galaxy.
The motion of air in atmosphere is called wind. So any thing flying be it bird or airplane are trapped in the movement of the wind.This movement is called drift. If there is no wind then ther e is no motion due to the drift.

it depends on what you are stationary in relation to. If you are in a geostatic orbit, you are stationary above one point of the Earth, so you would still be above your house.
If you are stationary independant of the Earth's rotation, you would first be going extremely fast (relative to the Earth), but you should wind up on the opposite side of the earth.

a plane flies with a speed relative to the air it's in... not relative to earth. Therefore, you would be at a distance of (speed of aircraft+speed of air)*12h from your point of origin.

Depends on if you are going east to west or west towards the east,but the atmosphere is moving so it really wouldn't matter would it?

very interesting question.
I imagine that you would be in a geosynchronous orbit with your yard because of gravity.
Lets not even get into wind effects.
I am no physicist that's just my opinion.

By your own question you answer your self,STATIONARY is STATIONARY you'd still be home.unless you meant something else!
