[PAR] [TLE] Reaction Engines Limited [SEP] Reaction Engines Limited (REL) is a British aerospace manufacturer based in Oxfordshire, England. [PAR] [TLE] SABRE (rocket engine) [SEP] SABRE (Synergistic Air-Breathing Rocket Engine) is a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air-breathing rocket engine.  The engine is being designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon spaceplane to low Earth orbit.  SABRE is an evolution of Alan Bond's series of liquid air cycle engine (LACE) and LACE-like designs that started in the early/mid-1980s for the HOTOL project.
