> We would build multiple layers of fuel oxidizer, and then, we would get a run long enough up to really do something. We’d get a really exciting event. I deemed it “pre-unplanned disassembly” at the time. That problem really went away when we learned a little bit about fuel control and kept injectors and propellant temperatures a little warmer.
