re: When Charlie Duke got back up!
Really interesting video Raoul!
The video I would point to (if I knew where to look) is the one of the Apollo Astronauts (I forget which one) carrying two experimental packages that kind of look like two box shaped barbells. These weights force his CG lower.
He is walking just like you or I! Not hopping or bouncing around! Of course his traction is also increased, but I think most of it is the CG being lowered.
