Not directly related to your question, but a humorous anecdote nonetheless: During one of my missions, Jeb was cruising along in my return vessel back to Kerbin from a successful Mun journey. I was going to try to do a pinpoint landing placing the splashdown just off the coast from the launchpad. However, tragedy struck while I was doing orbital corrections, I had not been monitoring my fuel! The rocket ran out, and even after using all RCS fuel at the apoapsis in a desperate attempt to bring it into atmosphere, the periapsis only brought the vessel in to about 75,000, which meant Jeb would never return to Kerbin! This would not do. However, I am also not skilled enough to attempt an orbital rendezvous. I was about to abandon the mission when my partner jokingly suggested to jetpack Jeb back into Kerbin. Now, I did not want to die from the fall, but it inspired a thought. Committing to the idea, the parachute-command module detached from the lander... At the apoapsis, I had Jeb EVA and jetpack-slam against the command module. Then, curious, I looked at the map. The periapsis altitude had been altered by the impact! Over and over again. It took probably 100 good slams, occasionally re-entering the command module to refuel his jetpack, before the orbit was decayed enough for re-entry. Jeb did not, in fact, get a water landing. Wasn't anywhere near the launchpad, either. But it was quite a feeling of victory when he got out and set foot on Kerbin again!
