Today I have a good excuse (as if one were needed) to show a photograph of a Saturn V, as it marks the anniversary of the launch by NASA, in 1967, of Apollo 4, the first “all-up” (everything in working condition) test of the Saturn V launch vehicle. Launch was at 7am, and the pointy end of the 363 foot (110 m) miracle of 1960’s engineering was parked into a 100 mile high orbit for two trips around the Earth, before the command module was splashed down into the Pacific Ocean, close to Midway Island.
The unmanned mission was deemed to have been successful, and involved placing the third stage, the S-IVB (pronounced “ess four bee”) and the CSM (Command/Service Module) into orbit, and simulating a return to Earth from a Moon mission.
Apollo IV was the first flight of NASA’s manned mooned mission after the Apollo I fatalities. There were unmanned flights between the two, but they have failed to attain the name Apollo II or III.
