Microsoft co-founder Paul Allen unveiled the world’s largest aircraft on Wednesday.
With a wingspan of 385 feet, the six-engine plane will be larger than Howard Hughes’ 1947 H-4 Hercules, known as the ‘Spruce Goose,’ and the Antonov An-225, a Soviet-era cargo plane originally built to transport the Buran space shuttle that is currently the world’s largest aircraft.
The Stratolaunch is an aircraft that is designed tocarry rockets between its two fuselages. In 2011, the project’s cost was initially estimated to be at $300million, though there is no word as to the updated figures.
After the plane reaches altitude, it would then drop the launch vehicle, which will subsequently fire its boosters and launch into space from the air.
