The S-IVB also ongoing to thrust in a very low degree by venting gaseous hydrogen, to keep propellants settled inside their tanks and prevent gaseous cavities from forming in propellant feed strains. This venting also preserved Secure pressures as liquid hydrogen boiled off from the gas tank. This venting thrust easily exceeded aerodynamic drag.[ci
