“The #Apollo4 Mission” (1967) - YouTube

This is an interesting documentary of the first #unmanned #flight of the #Apollo programme. From it, I learned that the reentry of the #CommandModule was done in two stages with an initial descent, followed by a partial ascent to cool off and then a final descent to the surface.
