Bryan;
The Nike system was the first air- defense missile that the US had. It
was designed soon after WW II so much of the technology was based on
German rocket research. At least they didn't use LOX & alcohol like the
V2. If those propellants didn't ignite at launch command they formed
very explosive ice pellets.

Good grief Neil.
RFNA and Aniline - ?? I don't think those two chemicals are allowed
in the state of Utah at the same time.
Wouldn't a nice little hybrid like the one used in SpaceShip 1
do the job? It would be cheaper because you wouldn't need to
supply heavy rubber SCUBA suits to everyone within 1/2 mile.
LOX & RP1 aren't any better.
Cheers,
Bryan
