Idea JBIS Interplanetary Project

[Tychonaut]

If anyone is interested in a current take on how a reusable launch vehicle / orbiter could have been done with '60s tech, the Journal of the British Interplanetary Society has a recent paper on the subject. The paper includes concept illustrations of the orbiter, two-stage reusable launcher, lunar lander and EDS, along with description and data on the design.
Could make a nice addon if someone feels like taking a crack at it.
