X-20X_
"Boeing intended the X-20 Dyna-Soar to be only the first in a series of spaceplanes. They developed variants for research, crew rescue, optical and radar reconnaissance, satellite retrieval and more. This is the X-20X, a follow-on version for space station ferry missions. The interior of the glider was substantially rearranged to provide for four passenger seats behind the pilot. The aft equipment bay was eliminated and all equipment was moved to the secondary power bay. The abort motor was eliminated. This resulted in substantial space and mass margins for large payloads in a bay in the transition section between the glider and transtage. Grappling arms provided for docking of the entire upper fuselage with a space station."
Dad was an NAA test engineer on the Dyna Soar project (1957 - 1963)
