Time to play some #KerbalSpaceProgram.
Today's hare-brained idea: Make a space-faring learjet.
Not a spaceplane. A totally normal-looking learjet with jet engines ONLY that has mostly-recoverable appendages for boosting it up into orbit, and RCS/OMS (maybe a Terrier for the OMS, puff engines are mad inefficient).
But once it re-enters, it shouldn't be distinguishable from a totally ordinary learjet once the RCS/OMS pods have jettisoned and parachuted down to the KSC. ;)
One of the difficulty is that while the mk2 parts are more heat-resistant and spacious (like a learjet), they don't look like a learjet, so I don't think I can use them. I'll have to stick with very BBQ-prone mk1 parts. But I do have one trick up my sleeve that I'll allow some rule-bending for: a single non-functional rcs port at the very nose of the plane to shield the cockpit from excess heat during reentry.
