The Dream Chaser™ spaceship has a long and successful history. The vehicle is based on the NASA Langley Research Center's ten passenger orbital HL-20, also known as the Personnel Launch System and the Space Taxi. The HL-20, in turn, was based on the Soviet BOR-4, and thus has significant orbital heritage. The Soviet BOR-4 (left) was a successful, orbital, autonomous re-entry vehicle, intended to be the basis of their human access to space. As the U.S. Shuttle was developed, the Soviet Union progressed to the BOR-5, and then the Buran, a copy of the U.S. Shuttle, leaving the safe and affordable BOR-4 behind.
