The project is being developed almost a decade ago by the company created by Paul Allen, one of the founders of Microsoft, who passed away last year before seeing the first flight of Stratolaunch.
It is the largest airplane in the world, composed of two twin fuselages, that are united through a wing with 117 meters, therefore larger than a soccer field. From nose to tail measures 72.5 meters and height is 15 meters, weighing 226 tons, a weight that can more than double with load. It is powered by six Boeing 747 engines.
The Stratolaunch is designed to be a satellite launch platform for Earth's low orbit and can significantly contribute to reducing the cost of these space missions. It can also help avoid embarrassment related to launches from Terra firme, related to weather or other conditions.
The maiden flight took about 2:15 and reached a top speed of 189 miles and an altitude of 15,000 feet. It was held in California, in the Mojave Desert.
