Replying to myself as the threads don't go any further.

But Slippage would indeed occur....but not just so close off the ground. It is light, and has been highly compressed....so not much needed to push it around near the ground but it isn't 'free' of forces.

The slippage occurs miles and miles up and is where the airplanes go up to do those weightless dives. That is where slippage will occur somewhat....so if they stay up there yes, they will lose or gain speed.
