Quick note that "Hazygreyart" on YouTube did a vid of this shuttle version launchingWhat if (and hear me out) we take a space shuttle orbiter and External Tank and stick them on top of a metholox converted Saturn-V first stage? No, you're right, it's nuts. It's not the '60s any more, who'd throw away an S1-C like that?
So what if we took that S1-C, then stuck wings and jet engines on it so it could fly back to base..?
This was an actual idea, seriously presented, by NASA in the 1980s as the sort of thing that would be needed to support Space-based Solar Power (SPS) satellites.
@e of pi challenged me to put this together based on models I already had, including the Space Lifter first stage from his and @Polish Eagle's excellent Right Side Up timeline.
