Guidance is a big no no because it’s bad for the whole hobby. We basically self govern so not to cause problems. People work on active vertical stabilization systems which is basically guidance for going straight up. No one attempts guidance to a specific destination because it’s a good way to put the whole hobby at risk. However, the skill and know how is there. People are putting passive stabilized rockets to 280k feet in black rock. A guy in Austin have active stabilization working above mach 1. It can be done within the hobby but no one wants to do it.

You can go see the most impressive ones launch at the annual BALLS event [1] in Blackrock desert several weeks after Burning Man.

The FAA closes off the airspace around the desert which allows the really powerful rockets to fly.
