As far as I know, Hybrid rocketry is limited to suborbital flights and amateur rocketry. I would like to know if there have been any rockets that made it into orbit, and what was the highest altitude a hybrid rocket has made it to?
This company is promising orbital access but I am unsure if the technology has already reached space and been demonstrated before. http://www.parabolicarc.com/2018/10/01/gilmour-space-raises-137-million-hybrid-launch-vehicle/
