The Conroy Virtus was a proposed American large transport aircraft intended to carry the Space Shuttle. Designed, beginning in 1974, by John M. Conroy of the Turbo-Three Corporation, it was to incorporate a pair of Boeing B-52 Stratofortress fuselages to form a new craft using existing parts for cost-savings.[1][2] While the project was seriously considered, it proved impractically large and NASA chose to develop the Boeing 747–based Shuttle Carrier from surplus commercial aircraft instead. - Wikipedia

-The Conroy Virtus could be equipped with scaffolding to carry or launch the Space shuttle under its center wings or could be equipped with a massive pylon to be able to carry a pod for the Rocket boosters

The closest thing to a real version ( my version is based off blueprints more and the pod is supposed to be more aerodynamic -it also opens-)

Controls are in game hope you have fun and enjoy!
