The S-IVB also continued to thrust in a reduced stage by venting gaseous hydrogen, to maintain propellants settled inside their tanks and forestall gaseous cavities from forming in propellant feed strains. This venting also maintained Risk-free pressures as liquid hydrogen boiled off during the gas tank. This venting thrust easily exceeded aerodyna
