Vulcan Aerospace Logistics Stratolaunch: Microsoft co-founder Paul Allen unveiled a colossal jet that will serve as an aerial platform launching low-orbit satellites.
The Vulcan Aerospace Stratolaunch carrier made its debut on Wednesday at a giant shed in the Mojave airport in California, where it has been under construction for the last four years.
The aircraft consists of two twin Boeing 747-400 aircraft and has six 747 engines. Stratolaunch will undergo aircraft, ground and flight feeder tests.
The Vulcan Aerospace Stratolaunch aims to carry rockets and satellites to around 30.000 feet. From this height the rocket will be released that will carry the satellite and put it into a low orbit. The aircraft will return to base of, will refuel and carry more rockets.
Galactic's Virgin Orbit plans a similar satellite launch service from a 747-400, called Cosmic Girl, which will carry Virgin's LauncherOne rocket.
Let's look at some of his technical features:
Its wingspan is 385 feet, or 117 meters, making the new aircraft slightly longer than the length of an NFL field and making it the world's largest aircraft, surpassing Howard's Spruce Goose H-4 Hercules Hughes.
The aircraft has a length of 238 feet (73 meters) from the cockpit to the tail, with a height of 50 feet (15 meters). Exit sheds were made for the first time to check the company if the 28 wheels of the aircraft can support its weight. 
It can take off with total weight 1.300.000 pounds (589670.081 pounds) and bring maximum payload up to 550.000 pounds or 249476 pounds. It has a 1.000 nautical mile radius.
Recall that Allen founded Microsoft with him Bill Gates in 1975 and remains a strategic advisor to the company, although he stepped down from the board in 2000. He has a net worth of $18,6 billion.
