The Stratolaunch, the world's largest plane, has been rolled out of its
hangar in the Mojave Desert.
The dual-hulled aircraft has a wingspan of 117m.
By comparison the Spruce Goose (Hughes H-4 Hercules) had a wingspan of 94m.
Funded by Paul Allen, the plane is designed to fly at an altitude of 30,000'
and launch the Pegaus XL rocket, built by Orbital ATK, into low-Earth
orbit.
