Mating and Demating a Space Shuttle — when NASA got sexy

The MDD essentially is a gantry structure supporting a large hoist (“lift beam” in NASA speak), like those seen at port facilities. The MDD is unique in that its design enabled the attaching or detaching of an orbiter to a modified Boeing B-747 Shuttle Carrier Aircraft.

This MDD consists of a pair of towers (100 feet/30.3m) supporting a horizontal structure 80 feet/24.2m above the ground which extends 70 feet/21.2m bearing the 120 ton force/106.8kN lifting beam. The MDD was designed by a firm in Coral Gables FL named Connell Associates — underscoring the technical and geographic reach of NASA needed to accomplish its missions.

NASA’s provides this MDD fact sheet.
