Impressive 1:8 scale model of the Boeing X-37A, also known as the Orbital Test Vehicle (OTV), built by Retro Rocket and used to develop a new process for showing the Thermal Protection System (TPS) using a 'trompe-l'oeil' technique to give it a realistic looking three-dimensional texture. The large model measures approximately 45″ in length with a wingspan of 22″, and mounted atop a wooden base measuring 14″ x 10″ x 1″ to a height of 17″. This impressively detailed model features the craft’s heat-resistant ceramic tiles, twin-angle tail fans, and both sides of payload bay area featuring craft designation and NASA and Boeing logos. The model was built using CAD data from NASA and is very accurate. In very good to fine condition, with scattered scuffs and soiling and some slight peeling to model panels.
