Some interesting footage, especially of the SA-5 and other Saturn I's. Shame it's all in that green tint, though.

That was awesome. I wonder if there is one on how LC-39 was converted for use for the shuttle program and how Apollo hardware was modified to fit the new vehicle?

It also wasn't de-interlaced properly - might have been due to youtube's transcoding. Anyone know a better source for this video? Avisynth can really clean it up.

After watching that, I really wonder how the piles the VAB is built on have stood up to corrosion over the decades. Being buried deep under the VAB there is no way to check or replace them.

Easy...
There was a corrosion protection

(but it is in french)

a copper grounding of steel piles

The building stood only a few feet above sea level and near the ocean. Salt water, saturating the subsoil, reacted with steel piling to create an electrical current. To prevent this electrolytic process from gradually eating away the steel pipe, workmen grounded the piling by welding thick copper wire to each pile and connecting the wires to the steel reinforcing bars in the concrete floor slab. Until this was done, the VAB could lay claim to being the world's largest wet cell battery
