The Federal Aviation Administration likely wont be ready to let commercial drones take to the skies in September 2015, despite a recent law directing it to do so, a government audit has found. The report, released last week by the Department of Transportations inspector generals office, found that the FAA is significantly behind schedule and that there are still significant technological, regulatory, and management barriers preventing the FAA from integrating drones into the national airspace. Those barriers include: failing to create standards that would allow drones to detect and avoid other aircraft, as well as ensure reliable connections with their controllers; Those recommendations will have the agency publishing an annual report, beginning November 30th, detailing its work toward safe drone integration.
