[Charlie is wearing John's camera.� He is holding the film magazine in his left hand and removes a dark slide with his right hand.� The magazine is a cube about 3 to 4 inches - 7 to 10 cm - on a side.]

[Charlie inserts the magazine at the back of the camera and then reaches down with his left hand to get the handle-mounted trigger and advances the film by one or two frames.]

[Charlie takes the CDR camera off his RCU bracket and puts it on John's seat.]

[Charlie grabs the MESA with his left hand and drops to his knees, illustrating the point discussed above.� He has to lean forward to get the sunshield and, as he rises, he hops forward, out of the TV field-of-view, to get his feet under his center of gravity.]

[Charlie has noticed an intriguing rock near the rack.� He tries to bob down to get it with his left hand.� He misses the rock and nearly falls.� He scrambles to his left to regain his balance.]

[This time, Charlie goes down on both knees and falls forward onto his hands as he grabs the rock.� He then pushes back a little and tries to run under his center of gravity;� He doesn't make it and falls back on hands and knees.]

[Once he gets settled, Charlie gives a hard push back with his hands and, as his PLSS rotates over his knees, he stands without much difficulty.� This is the standard technique.� Once on his feet, Charlie examines the rock, turning it as he tries to find a clean surface.]

[Charlie removes the dark slide from the new magazine and puts it in the seat pan.� He raises the magazine to his faceplate.]
