when I said "it just doesn't".

What IS the straight answer? The dropping something in a moving vehicle
analogy doesn't work, does it? A plane has a method of acceleration, whereas
a passively dropped object doesn't.

Sometimes really simple questions can give you the worst time.

Because when you leave the earth you are traveling the same relative
speed as the earth as is the atmosphere in which you are traveling.
