These studies soon morphed into bona fide vehicle development programs, with the U. The X rocket plane was one result. This vehicle made nearly test flights from to It reached outer space, which officially begins at an altitude of 62 miles kilometers , on several occasions.
And the X still holds the world record for fastest manned rocket-powered aircraft, reaching a top speed of 4, mph 7, kph during one test flight. Around the same time, the U. Air Force was working on the X space plane, known as the Dyna-Soar. This vehicle — similar to today's space shuttle in design — was slated to be used for a variety of purposes, including reconnaissance and satellite maintenance.
The Dyna-Soar was almost built, but not quite. The program was cancelled in , after construction had already begun. Development of the X and the Dyna-Soar, along with other vehicles such as the HL, helped lay the foundation for the space shuttle program shortly thereafter. As the s wore on, reusable shuttlelike space planes were increasingly viewed as key to the nation's ability to access, explore and exploit space.
Their importance was cemented in the so-called "von Braun paradigm," an idea widely circulated at the time by the famed German rocket engineer Wernher von Braun. Von Braun came to the U.
