The Boeing X-20 Dyna-Soar Spaceplane is a hypothetical concept conceived by Boeing, NASA, and the US Air Force in the pioneering era of spaceflight for its sleek reentry system often misleadingly compared to the Shuttle. The program was abandoned in favor of standard space capsules but never significantly influenced the Shuttle's design that emerged later. However, it would have been an innovative vehicle had it seen development. Unfortunately, no prototypes were built, resulting in varied sketches and mockups; nonetheless, a good idea exists of what the concept would resemble, which I've represented in a scaleable model capable of being printed down. Weighing 6.4 meters across, it was much smaller than its Shuttle counterpart, set to be launched atop a modified Titan rocket in the style of a capsule – significantly more subdued compared to contemporary capsules with respect to propulsion; though RCS and a maneuvering system would've offered basic control capabilities. After reentering Earth's atmosphere once, this aircraft diverged from typical space capsule protocol: It conducted long gliding passes soaring, gliding downward periodically as it gradually descended further, slowing steadily before landing.
