Actually, the odds of the fuel making back down was pretty good. Hydrazine is incredibly dangerous and carcinogenic. Not to mention that fuel is hypergolic.
Back in the olds days, drag racers tried adding it to their fuel, and in a 1% solution, it would boost horsepower something like 100%. Many engines didn't make it 100 ft. before coming apart at the seams. It was quickly banned by the NHRA (and rightfully so).
Missiles were my specialty in the Army. All I can say, is nice shot, very impressive! Wish I could have been in on it!
