Paul Allen, the co-founder of Microsoft, has taken on Burt Rutan as his partner in his plan to design the world’s largest aircraft. Rutan is recently retired from Scaled Composites, the company he founded in Mojave, California. Allen is no stranger to the world of aviation – he was the funding behind the SpaceShipOne, the first privately funded manned rocket. His most recent endeavor is his company, Stratolaunch Systems. The objective for Stratolaunch is to deliver payloads (including people) to orbit Earth.
