How did this work in real life? You had a rocket like a bomb in the hangar all the time? Was it ready to be fired anytime or secured somehow? Solid fuel rockets burn out whenever they are activated. And do you drop them after use? Glowing hot parts? This sounds more like a project, did anybody ever actually use it, get a demo or similar?
I only know the military JATO/ATO and they treat it with ultimate respect because it is so dangerous.
