Australian and US scientists successfully launched a supersonic scramjet engine at an Outback test range Friday, as they work on a device that could revolutionise air travel.
The researchers said a rocket carrying the scramjet reached speeds of mach 10 — ten times the speed of sound — after blasting off at the Woomera range in South Australia Friday.
They said it reached an altitude of 530 kilometres (330 miles) before the scramjet was successfully deployed following re-entry to the Earth's atmosphere.
Australia's Defence Science and Technology Organisation (DSTO) said it was believed to be the first time a scramjet had been ignited within the Earth's atmosphere.
