Big Test To work at Mach speeds, the rocket engine has to endure extreme high temperature airflows.  Engineers at Reaction Engines LTD in the UK have designed a heat-exchanger to make that happen.  At the Colorado Air & Space Port in the US, it just successfully endured a major test.  In simulations it handled flying at 3 times + the speed of sound.  In less than 1/20 of a second, the heat exchanger handled and "quenched" a 420C onslaught of airflow.
