World’s widest plane completes second test flight in California


The massive Stratolaunch — an airplane with the world’s longest wingspan, powered by six engines — flew this week for the second time over the Southern California desert. The catamaran-looking aircraft, which features two cockpits on separate fuselages, took off Thursday from the Mojave Air and Space Port two years after its maiden flight, following a change in ownership and purpose. “We are airborne,” the Stratolaunch company tweeted about 7:30 a.m. The plane, a behemoth with a wingspan of 385 feet named Roc, reached a maximum altitude of 14,000 feet and a top speed of 199 mph during Thursday’s test flight, according to It landed safely about three hours later on its 28 wheels — and Stratolaunch called the test a success.
