In partnership with Scaled Composites, Stratolaunch successfully completed the first flight of the Stratolaunch aircraft. As part of this initial flight of the world’s largest aircraft, the pilots evaluated aircraft performance and handling qualities of the all-composite, duel-fuselage design. The airplane took off at 0658 PDT on April 13, 2019, from the Mojave Air & Space Port, and flew for 2.5 hours, achieving a maximum speed of 189 miles per hour and reaching altitudes of up to 17,000 feet. The plane landed safely amid cheers from the team that designed and built the plane.
