The first view is a close-up of one of the five main engines on the Saturn V, and the second clip is looking toward the 2nd, 3rd stages with the lander and command module at the far end. Then, a view back along the first stage. Rate of fuel consumption on the first stage is truly astronomical. Really huge system!

The audio-visual shows are awesome... Well, that applies to the whole Saturn V - Apollo building. Can't believe it took us over a year to get around to seeing this part of the Kennedy Space Center... Absolutely the best part!
