On Wednesday 31.05.2017, Microsoft co founder unveiled what is now being called the world's largest aircraft.
It boasts of having six boeing 747 engines with a wingspan of roughly 384-385 feet which by far is the longest wingspan known.
It was designed by Scaled composites,one of Allen's partner at Stratolaunch Systems, which coincidentally is owned by Paul Allen's firm.
The design of a Stratolaunch is done to carry rockets between te fuselages.
The project's cost as at 2011 was initially estimated at around $300million, though it is expected for the figures to have been more than that right now.
At a certain altitude, the plane drops the launch vehicle, subsequently firing its boosters and launching into space from the air.
With the plane having an estimated weight of around 500,000 pounds without any cargo.
The design was meant to carry a maximum takeoff weight of around 1.3million pounds.
The aircraft is being kept at a hangar in California.
Movement is easier for the aircraft with the 28 wheels design and being powered by the boeing 747 engines makes it cooler
