NOT KNOWN FACTS ABOUT APOLLO 3.5 BLUE PLUS PROCESSOR

The S-IVB also ongoing to thrust at a small level by venting gaseous hydrogen, to maintain propellants settled of their tanks and forestall gaseous cavities from forming in propellant feed lines. This venting also preserved Risk-free pressures as liquid hydrogen boiled off from the gasoline tank. This venting thrust very easily exceeded aerodynamic
