Some of the design features of the Grumman Design 619. Compared to the Shuttle Orbiter as actually built, the most obvious difference is the inclusion of the air breathing propulsion system model that consumes about 1/3 of the payload bay. Also note the RCS modules on the wingtips, the outward-bowing payload handlers station, nose airlock and the solid abort rockets along the aft fuselage.
Very interesting- so the 4 air-breathing engines were carried into space and back? Or were they just installed for ferrying? Where was the fuel for them stored? Perhaps in place of cargo in the main bay?
