'"It is a game-changing technology... and could revolutionise global air travel, providing cost-effective access to space," Australia's chief scientist Alex Zelinsky said in a statement.
'Scientists have said hypersonic technology could cut travelling time from Sydney to London to as little as two hours for the 17,000-kilometre (19,540-mile) flight. Hypersonic flight involves travelling at more than five times the speed of sound (Mach 5).
'Scientists involved in the programme -- called Hypersonic International Flight Research Experimentation (HIFiRE) -- are developing an engine that can fly at Mach 7, Michael Smart of the University of Queensland told AFP.
'"It's an exciting time... we want to be able to fly with a hypersonic engine at Mach 7," said Smart, a hypersonics expert involved in the programme which also includes US aerospace giant Boeing and German space agency DLR.'
