The loss of the Falcon HTV-2 hypersonic aircraft last summer was caused by the vehicle's skin peeling away, DARPA has revealed.
The Army yesterday carried out its first test flight of a hypersonic missile that has a worldwide range.
DARPA has released video footage of the Falcon HTV-2 flight earlier this month, which ended unceremoniously after just three minutes when it lost contact with the vehicle. And, guess what, DARPA says the flight was a great success.
An experimental vehicle that can fly at 20 times the speed of sound and reach anywhere in the world within an hour is due to lift off today.
NASA's planning to spend $5 million a year over the next three years on the development of a hypersonic vehicle that could fly at five times the speed of sound.
US and Australian defence scientists have made a second test flight of a hypersonic rocket, with the aim of gathering data to commercialize the technology.
