- Gary where did you get this info? I went over to the Alabama Space and
- Rocket Center and looked at the Saturn IB there and looked at some of the
- drawings that I happen to have inherited from some of my German friends and
- they engines and tanks sure look independant to me. There are 8 tanks,
- eight engines, eight sets of propulsion plumbing. The beauty of the
- design is that if one engine goes south then you do not lose the mission due
- to some screw up in the fuel system. The rocket team was working on an
- extremely tight budget on the Saturn I stage. It was completed and tested for
- the first time BEFORE the Army Ballistic Missile Command was transferred to
- the Jurisdiction of NASA. (ground and not flight test) The first flight
- of the Saturn I was before the Gemini launches on the Titan II. I think it
- was in 63. A good book on the early days of the Von Braun team at Redstone
- Arsenal and a good prophetic insight on the burgeoning NASA space program
- is to be had in "Count Down To Decision" By General Bruce Medaris, Who was Von
- Brauns boss at the ABMA. It also tells how the Saturn I was funded as well
- as the Redstone. One funny story in the book describes the idiotic
- budgetary constraints that would not let Von Braun order a typwriter for
- his secretary, so they ordered a "rotary data recording device". That
- got through the purchasing department like a breeze. You are right that the
- avionics were new, so will the Delta's in a clustered set up.
