Re: "unofficial" information



As a former Titan II ICBM crewmember, I can assure you a full gravity
environment doesn't effect the quality of fuel storeage nor the system.  The
Titan II held thousands of gallons of nitrogen-tetroxide and UDMH
(unsymetrical-dimethyl hydrazine) without problems except when us humans
tried to mess with it.  In stainless steel vessels and plumbing, fuel and
oxidizer can be stored long term without incident.
