Superjet technology nears reality after tests

A two-hour flight from Sydney to London is a step closer to reality after the latest successful test on Wednesday of hypersonic technology in the Australian desert.

A joint US-Australian military research team is running a series of 10 trials at the world's largest land testing range, Woomera in South Australia, and at Norway's Andoya Rocket Range.

"It is a game-changing technology ... and could revolutionize global air travel, providing cost-effective access to space," Australia's chief scientist Alex Zelinsky said in a statement.
