- I can buy the four engines and 6 engine bit, but according to document I
- have found here and the Book "Rocket Scientist" and Medaris's " Cound down
- to Decision" These were desginated the Centaur, although I will go back and
- look and make sure of this just in case.

- According to Dr. Sthulinger and Konrad Dannenburg the C-1 designation was
- dropped when the CSM was put on the stack. This is confirmed by the models
- that I saw yesterday and the Museum piece out at the Arsenal that is
- designated Saturn C-1. The Saturn 1 with an Apollo CSM is the one on vertical
- display at the Alabama Space and Rocket Center. There is also an Saturn C-1
- out at the Alabama State line at the vistor center.

- From my information this was always the program intent of the Saturn 1B. This
- helped to lower the costs for the test program of the full Saturn V by flying
- most of the Saturn V hardware before the big bird was ready. According to
- folks here at MSFC the 1B could lift that weight. The models that are on display
- at both the Alabama Space and Rocket Center and in the Headquarters building
- at Marshall show the full Saturn V payload on the 1B stack.

- Remember that the ASTP payload was the full up CSM as well as the docking
- adaptor and the launch was to a 51 degree inclination orbit. This easily
- equals the weight of the Lunar Module in a 28.5 degree orbit.
