Stratolaunch, the launch venture created by Microsoft co-founder Paul Allen, took the world’s biggest airplane out of its hangar this weekend at California’s Mojave Air and Space Port and revved up its engines in preparation for the next step toward shooting rockets into space from midair.
The rocket-launching part is still a year or two away, but Stratolaunch is aiming to put the 385-foot-wide, twin-fuselage plane through its first test flight within the next couple of months.
