Hyshot tests hypersonic "scramjet" in Australia
A supersonic jet engine known as a "scramjet," which could substantially reduce air travel time has been tested at Woomera, in South Australia's far north. An international team launched the Terrier-Orion rocket carrying the hypersonic scramjet—an oxygen-sucking supersonic combustion ramjet engine. The rocket took the prototype aircraft to an altitude of 314km (195 mi) before crashing ten minutes later, a spokeswoman for the Hyshot program said. A supersonic boom was felt across the Woomera test range seconds after the jet took off. The Queen
