There are other things that could affect it at that height though, like temperature, moisture, air pressure and so on, which are all very different to normal conditions here on the ground.

Once it hits the lower atmosphere it's going to drop only about as fast as it would from a couple hundred feet, regardless of the things you mention.


It will travel faster in the upper atmosphere, but by the time it gets to a lower altitude it will slow down and as I said, it won't be traveling any faster than if they dropped it off a moderately tall building.
