The LAPCAT A2 will be able to “pretty easily” fly around the world at an incredible Mach 5 - five times the speed of sound. The precooler system weighs around a tonne, and, as Business Insider explains, is made up of a swirl of thin pipes that are filled with condensed helium. These pipes suck heat from the air, cooling it down to -150 degrees Celsius before it enters the engine.
