Hi guys..i been thinking of this since my primary school..hope anyone can answer this wit details explanation!?

If a helicopter start flying upward and stand still at the air at the same place for about lets say 3 or 4 hours...when it come down landing back..will it land at the same place?..why i ask..facts...earth is rotating at its axis rite..if im not mistaken 1 hour equal to 15 degrees..so if the heli stay still at the air will it land at the same place after 4 5 hours?..or will it come down at different places?...or will it land at the same place because the gravity of the earth pull it together when rotating that will make it landing at the same place?..come think about it..maybe we need mythbusters this time..:)..sorry bad english..
