Stratolaunch, the aerospace venture founded by the late Microsoft co-founder Paul Allen, sent the world’s biggest airplane into the air today for its first flight test.
The twin-fuselage plane, which incorporates parts from two Boeing 747 jumbo jets and has a world-record wingspan of 385 feet, took off from Mojave Air and Space Port in California for a flight that lasted two and a half hours.
For more than seven years, Stratolaunch has been working with Mojave-based Scaled Composites on the project, which aims to use the plane as a flying launch pad for orbital-class rockets. The first flight test had been anticipated for months.
“We finally did it,” Stratolaunch CEO Jean Floyd said today during a briefing.
