F-1 Engine Thermal Protection System Photos

At last, here are two photos of the Thermal Protection System used on the F-1 engines of the S-IC. Previously, I have refered to this as "foilbatt insulation" which is a generic term. I have enlarged sections of each photo to show details. The first image is of a single engine test, while the second image with the other F-1's visible is of S-IC-T. The F-1's are early versions, but the TPS system would have been almost identical with only minor changes.

These photos are courtesy of Rocketdyne.
