Earlier this week Allen put on display for the first time his huge new plane, built by the secretive Vulcan Aerospace (which Allen owns) over the last six years in a massive hangar at the Mojave Air and Space Port in the high desert north of Los Angeles. The Stratolaunch features not one, but two large fuselages connected by wings that stretch 385 feet across. That’s 25 feet longer than a football field, end zones included. The Stratolaunch has 28 wheels and will be powered by SIX huge jet engines similar to the four that hang on the wings of Boeing 747s.
