Quote:After the better part of a decade of development, we are getting our first glimpse of Stratolaunch's massive mothership outside her low-slung hangar at Mojave Air and Space Port. As expected, the size and design of the huge and exotic aircraft is impressive to say the least. At 385 feet wide, it has the longest wingspan of any aircraft in the world—even longer than the record-setting Hughes H-4 Flying Boat, aka the "Spruce Goose." Loaded fully, it will tip the scales at a whopping 1,300,000 pounds, and is powered by six Pratt & Whitney PW4056 turbofan engines—the same engine that powers many 747-400s—putting out a combined 340,500 pounds of thrust. 

There is no doubt about it, Stratolaunch has given birth to a truly technologically wondrous machine.
