The fuel was Aerozine-50 and the oxidizer liquid nitrogen tetroxide (N2O4.) Aerozine-50 is a 50/50 mix of Hadradize (N2H4) and Unsymmetrical dimethylhydrazine (UDMH) (1,1-Dimethylhydrazine). The two are hypergolic. Nitrogen tetraoxide and hydrazine (in monomethyl hydrazine form) are use in the Space Shuttle's orbital maneuvering system.

NO2 in vapor, NO2 and O2N-NO2 mix in liquid, pure dimer as a solid. Boiling point 21C

N2O4, not NO2

Titan silos are long-defunct now. Few are even available for sale. This pic is taken I think in Titan museum in southern Arizona, about 1 hour drive from Tucson. The figures seen in the silo are manequins. The reason why they had to wear full bunny suit is that the oxidizer and fuel, NO2 and dimethylhydrazine, are super poisonous, corrosive and and burst in flame when mixed together. One good lungful of the vapors and you aend up on intensive care. The fuels were stored outside the missile and refueled just before the launch. Apart from eating lungs and metals, NO2 also had unpleasant tendency to freeze in cold temperatures. Nowadays all rockets are solid-propelant-based.

um, platforms? Like the one the two techies are standing on. They fold down when the missile is inspected.

anybody knows what those radiator-like thingies in the upper part of the silo are?
