Roc Engenders Speed Metal
Stratolaunch, the Seattle-based aerospace company and hypersonic flight-test pioneer, cut short a test-flight of its mammoth carrier aircraft, Roc. The twin-fuselage, six-engined, high-wing, mono-plane—which takes its name from the Roc, an enormous mythological bird of prey—has been undergoing flight-testing at Mojave Air and Space Port in preparation for upcoming missions during which it will serve as a launch-vehicle for rocket-powered, hypersonic, test-aircraft.
