NO NO NO NO NO!!!! The Redstone booster was a liquid fueled vehicle, as was the Atlas, the Titan, AND the USSR's RD-107 standard booster (used for Vostok, Voskhod, Sputnik, etc). The RD-107 was a low-tech booster with a cluster of 20 fairly small kerosene/LOX motors running at about 1100 psi chamber pressure but it was indeed a liquid burner. The Shuttle is the first attempt anywhere that I know of to actually build man-rated solid motors (although they would have been used on the Titan 3 which would have lofted the Air Farce (-: MOL project, which was cancelled). I think we've paid pretty dearly for this so called 'cost saving' on those solids. -- Mark Johnson (Mark.Johnson@Wichita.NCR.COM) NCR Engineering & Manufacturing-Wichita, KS phone: (316)636-8189 email:...!rutgers!hplabs!hp-sdd!ncr-sd!ncrwic!encad!mjohnson US snailnet: 3718 N.
