The space plane, dubbed Skylon, only exists on paper. “The gateway is now open to move beyond the jet age.” “One of the major obstacles to a re-usable vehicle has been removed,” he said. ![]() “ESA are satisfied that the tests demonstrate the technology required for the Sabre engine development,” the agency’s head of propulsion engineering Mark Ford told a news conference. That ambition was given a boost on Wednesday by ESA, which has acted as an independent auditor on the Sabre test program. Reaction Engines Ltd believes its Sabre engine, which would operate like a jet engine in the atmosphere and a rocket in space, could displace rockets for space access and transform air travel by bringing any destination on Earth to no more than four hours away. A small British company with a dream of building a re-usable space plane has won an important endorsement from the European Space Agency after completing key tests on its novel engine technology. ![]() A Skylon in flight with a cutaway of the SABRE engine, in an illustration courtesy of Reaction Images Ltd.
