Same gravitational acceleration of unequal masses

D H

An earth bound observer is not in an inertial frame, no matter how you cut it.

Newtonian mechanics. The Earth is accelerating toward the object. An accelerating frame is not inertial in Newtonian mechanics.
General relativity. A stream of falling apples accelerates with respect to the observer. A frame with a stream of falling apples is not inertial in general relativity.
