stjobe writes: Sydney Morning Herald reports:

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.

One could understand why Microsoft put the activation process into place, with all the pirating that was taking place with early verisons of Windows. Now Microsoft has taken authentication of the Microsoft Validation to a whole new level. Starting now, they will be checking your operating system every month."
