NASA unmanned Ikhana aircraft makes history flying without escort

This isn’t your grandma’s drone. NASA‘s Ikhana aircraft looks like a full-sized airplane, but there’s something important missing. There’s no pilot on board.  The Ikhana passed a milestone for unmanned aircraft by flying in public airspace without a safety chase plane for the first time. NASA got special permission from the Federal Aviation Administration to conduct the test flight. “This historic flight moves the United States one step closer to normalizing unmanned aircraft operations in the airspace used by commercial and private pilots,” NASA says. The plane is remotely operated by a pilot on the ground and is equipped with a host of high-tech systems that help it navigate and avoid mid-air collisions or close calls. The detect-and-avoid technologies include an airborne radar system and a satellite positioning system that broadcasts Ikhana’s position to other planes. Ikhana took off from Edwards Air Force Base in California and cruised at an altitude of 20,000 feet (6,100 meters) through airspace shared with commercial flights. It later descended to a lower altitude shared with general aviation flights.
