Great Video – Thanks John.

I especially liked the part at 1 minute into the video when the wheels suddenly pop out!

Also – This clip has a very clear section demonstrating the communication time delay. At about 2:08 into the clip Dave Scott mentions that the walking hinges are unlocked and ground control answers that they are supposed to be. You hear both loops so you hear ground control answer (on the ground loop) then you can hear the answer again on the Astronaut loop (several seconds later)!
