In the movie they docked to Endurance with the Ranger at about 68 RPM's. Once docked they retarded the spin by using thrusters which looked like it was from the Ranger. I can think of two scenarios:

1. The Endurance had thrusters which fired when the Ranger docked. Which begs the question why not use wireless means to fire the retro thrusters instead of needing to dock?
2. The retro thrusters were fired by the Ranger so that the physical connection to Endurance would also slow down as the Ranger slowed. But I find that hard to stomach because the sheering force on the docking port would be so great it would snap in two.

I was curious if there was anything further I was missing?
