I know its literally rocket science and a lot of very complex systems need to work together, but shouldnt we be able to iterate on a working formular?

Well, besides the fact most rockets are designed to self-destruct if they lose control or go too far off course, truth is, rockets are complicated. It’s easy to build a rocket design that does the same thing over and over again. Hell, SpaceX has managed to even make boosters reusable. However, if something goes wrong, they tend to go wrong explosively, as the only difference between a rocket engine and a bomb of several kilotons is the rate at which the detonation happens, because a rocket engine is basically a controlled explosion. I mean, in a sense, so is an internal combustion engine, but the difference here is that a rocket, since they are generally headed to space, as to bring an ignitable mixture of fuel. A car can afford to just suck air in from the enviornment, a rocket can’t.
