VIDEO: Reaction Engines is Working on an Aircraft That Could Fly Anywhere in the World in Just Four Hours

British aerospace is working on an aircraft that can do just this and would also be able to fly in outer space. They are working on a truly new technology that would make this possible. It is called the precooler. Air that enters the new “Sabre” engine system could be cooled by more than 1,000 degrees Celsius in .01 seconds. This could make the jet engine run at higher power, and more power is more speed, it maybe even enough to fly at Mach 5. Watch the video below:
