World’s largest plane makes first test flight
The world’s largest airplane — a Stratolaunch behemoth with two fuselages and six Boeing 747 engines — finally made its initial test flight on Saturday in California.
It was made by an engineering company called Scaled Composites.
The airplane is so big its wings are longer than a football field, or about 1.5 times that of an Airbus A380.
Stratolaunch behemoth hit a top speed of 304 kilometers per hour and touched an altitude of 17,000 feet, or 5,182 meters.
Stratolaunch was financed by Paul Allen, a co-founder of Microsoft as a way to get into the market for launching small satellites.
