The Stratolaunch, the world's largest aircraft by wingspan, completed its successful first flight over the Mojave Desert, California, on Saturday.
The Stratolaunch has six engines and has a wingspan of 117m (384ft), bigger than the length of an American football field.
According to official information from Stratolaunch, the aircraft reached a maximum speed of more than 300 kilometres per hour (189 mph), during its 2.5 hour long flight at altitudes up to 17,000 feet (5,181m) over the desert.
According to reports, the Stratolaunch will enable convenient and affordable access to space, as its centre wing is designed to carry as many as three satellite-laden rockets and can support multiple launch vehicles, weighing up to a total of 500,000 pounds (over 226 tons).
