Not really , but your mom stood no chance at all of getting her
hands on
propellant . They watched it pretty close , the formula was a secret
back then . Might still be , but I can't remember now just what was
in it .

Not really so secret. I got lucky enough to meet and become good
aquaintances with the guy who originally formulated the SRB package. He
is not well now - very advanced in age - but lives in Utah, and still
sells the surplus chemicals that Morton Thiokol rejected on QC issues.
He has tons and tons of the stuff, and lots of amateur rocketeers get
their chems from him.

It's basically ammonium perchlorate, HTPB (or now CTPB) rubber, aluminum,
iron oxide, and carbon, cured (then, at least) by an isocyanate curative.

I still have a few "kits" of the stuff.
