lightweight heat exchangers capable of cooling airstreams from over 1800°F to -240°F

This engine is a true potential game changer as far as known propulsion is concerned. It could become the engine that powers the first jet/shuttle hybrid aircraft.
It will dramatically decrease the cost of putting payloads in orbit, and decrease flight times between different parts of the world.
Im just hoping it stays uk based and we develop the infrastructure to support it here. It would provide a massive economic boost to remote areas of the UK. We are already one of the world's top manufacturers of satellites for commercial use, so offering both the tech to both launch and produce satellites cheaply would be a major coup.

Off-topic, but have people seen this space simulator? The craft and missions get really interesting, all "real" physics....
Oxfordshire-based Reaction Engines has successfully tested its innovative precooler at airflow temperature conditions representing Mach 5, or five times the speed of sound, marking a significant milestone in the development of its SABRE™ engine and paving the way for a revolution in hypersonic flight and space access. The precooler heat exchanger is a vital component of Reaction Engines’ revolutionary SABRE air-breathing rocket engine and is an enabling technology for other precooled propulsion systems and a range of commercial applications. This ground-based test achieved the highest temperature objective of the Company’s HTX testing programme and took place at its specially constructed unique facility at the Colorado Air and Space Port, United States. During the latest series of tests, Reaction Engines’ unique precooler successfully quenched airflow temperatures in excess of 1,000°C (~1,800°F) in less than 1/20th of a second. The tests demonstrated the precooler’s ability to successfully cool airflow at speeds significantly in excess of the operational limit of any jet-engine powered aircraft in history. Mach 5 is more than twice as fast as the cruising speed of Concorde and over 50% faster than the SR-71 Blackbird aircraft – the world’s fastest jet-engine powered aircraft. This most recent test builds upon the success of previous HTX hot tests undertaken in April which saw the precooler successfully operate at temperatures of 420ᵒC (~788ᵒF) – matching the thermal conditions corresponding to Mach 3.3 flight.

Yes it's excellent although last time I was on it my Kerbal got stuck in orbit on another planet he's still there to this day.
