World's Biggest Plane & Hypersonic Travel
Stratolaunch's Roc Carries a Hypersonic Vehicle to 23,000 Feet Source: Stratolaunch Major Moves Toward Hypersonic Commercial Flying at Mach 6 The world's largest airplane, California-based Stratolaunch's Roc, with a wingspan longer than a football field, just aced a major test flight while carrying a hypersonic prototype plane. The success is important on a number of levels.
