"The propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent)."

A NASA engineer happened across a rare, color photo of the Hindenburg disaster at Lakehurst, N.J. He immediately recognized that the 'color' of the flames could not be associated with 'hydrogen.' He was able to obtain a very small sample of the Hindenburg's outer envelope, and learned that the outer surface was coated with nitrocellulose ( gun cotton ) dope containing aluminum powder ( as a UV protectant ). 'Rocket fuel'.
He was able to introduce an artificial static discharge, which ignited the cloth, with intense flame spread.
