Sarcasm aside, I'm still mourning the loss of a real hero. Dr. Karl Klager. He made the fuel for the 3,4,&5 stages. He did all our rocket fuels. This country gained much when he came and lost much with his passing.
Us rocket guys say, "propellant", not "fuel". Fuel is usually one-half of propellant.
Apollo used no solid fuels except on the escape rocket. It was powered by liquid oxygen, kerosene (RP-1), and liquid hydrogen. I do not believe Dr. Klager had any part in any of those substances.
