I\'ve seen videos of rockets that jettison their SRBs but keep their main liquid fuel engine burning. How does that work? When I do it, if I put the SRBs on the same stage as the main LFE and hit space to jettison the SRBS I obviously decouple the main engine. How do I get rid of the solid boosters and keep the main engine? I don\'t know if I\'ve explained myself well enough or not, I\'m sorry.
