Do you have any information about so- called hybrid rockets? The only think I know about them, is that this type of rocket is uncrewed and guided and used for test in under microgravity conditions. I wanna know why it is exactly hybrid and are there some crewed rockets like that?

Apparently, Virgin Galactic's Spaceship One passenger rocket used a hybrid rocket.
- It has carried out crewed test flights, but has not entered commercial service at this time.
