This subject has been mentioned on this blog before (way back in 2008, 2012, and 2013), but here’s a brand-new video covering the subject of the inconel foil insulation that protected the F-1 engines on the Saturn V when they flew. This insulation was rarely seen by the public and made the engines look entirely different from what people were used to, because the insulation was something of a last-minute addition to help counter some severe heating cause by exhaust gas recirculation as well as direct thermal radiation roasting of the central engine.
