We gotta figure out a better way than strapping ourselves to a continuously exploding bomb and pulling some serious Gs for 8 minutes.

Wonder how some of those SSTO space plane projects are doing...there was a British one I can't remember. Used hybrid air-breathing scramjets, switching to internal oxidizer once it was going fast and high enough.

Edit: here is is and I was mistaken it's not a SCRAMjet https://en.m.wikipedia.org/wiki/Skylon_(spacecraft)
