The aircraft is so big its wing span is longer than a football field, or about 1.5 times that of an Airbus A380 WASHINGTON: The world’s largest airplane — a Stratolaunch behemoth with two fuselages and six Boeing 747 engines — made its first test flight on Saturday in California. The mega jet carried out its maiden voyage over the Mojave desert. It is designed to carry into space, and drop, a rocket that would in turn ignite to deploy satellites. It is supposed to provide a more flexible way to deploy satellites than vertical takeoff rockets because this way all you need is a long runway for takeoff. It was built by an engineering company called Scaled Composites. The aircraft is so big its wing span is longer than a football field, or about 1.5 times that of an Airbus A380. Specifically, the wing span is 117 meters; that of an Airbus A380 is just under 80. The plane flew Saturday for about two and a half hours, Stratolaunch said. Until now, it had just carried out tests on the ground. It hit a top speed of 304 kilometers per hour (189 mph) and reached an altitude of 17,000 feet, or 5,182 meters. “What a fantastic first flight,” said Jean Floyd, CEO of Stratolaunch. “Today’s flight furthers our mission to provide a flexible alternative to ground launched systems,” he added. Stratolaunch was financed by Paul Allen, a co-founder of Microsoft as a way to get into the market for launching small satellites. But Allen died in October of last year so the future of the company is uncertain
