This artist’s conception showed the X-37 Advanced Technology Demonstrator in the Shuttle Payload Bay. The X-37 lies on a pallet, with the Earth in the background and the Sun rising on the right. Rounded on the top and flat on the bottom, the X-37 design incorporated double-delta wings and two horizontal stabilizers, forming a V-shape.1999NASA Photo › X-37 Project Description
