The Federal Government says Australian and US defence scientists have successfully tested a hypersonic aircraft for the second time in South Australia's outback.
The aircraft soared through the atmosphere at more than 5,000 kilometres per hour after taking off from the Woomera Test Range.
The experiment was first conducted in May last year and more tests are planned.
Hypersonic flight could potentially allow people to travel between Sydney and London in just two hours.
