Legacy
Despite cancellation of the X-20, the affiliated research on spaceplanes influenced the much larger Space Shuttle that would also be boosted into orbit by large rockets. The final design also used delta wings for controlled landings. However, it did not fly until decades after the X-20 program was canceled. The later, and much smaller Soviet BOR-4 was closer in design philosophy to the Dyna-Soar, while NASA's Martin X-23 PRIME and Martin Marietta X-24A/HL-10 research aircraft also explored aspects of sub-orbital and space flight.
