Douglas design of the early 1960's for a two-stage-to-orbit, winged, recoverable vehicle. Two versions were envisioned - a preliminary one the size of a DC-8 and a monster vehicle capable of delivering one million pounds payload to orbit. It was assumed at this scale that Lox/LH2 vehicles could achieve stage propellant mass fractions of 88% to 86%.
