DARPA attempted for the second time to fly the fastest aircraft
ever built Thursday. The Agency's Falcon Hypersonic Technology
Vehicle 2 (HTV-2) is designed to fly anywhere in the world in less
than 60 minutes. This capability requires an aircraft that can fly
at 13,000 mph, while experiencing temperatures in excess of 3500F.
The second test flight began with launch at 0745 Pacific Time.
