I’m 5mins in on looking at this SABRE and it’s doing my brain in lol Mach 5 is around 9-10k km/h you need 11-12k km/h to reach escape velocity (I think the Saturns were hitting 13+k km/h). So that final push when it switches to rocket is what will give it the extra oomf to reach low orbit. It’s still carrying a fuuckton of fuel though. So weight, thrust, parabolic trajectory, distance will still be the same as conventional? Or am I wrong?
