The Federal Aviation Administration is making progress in its efforts to integrate unmanned aerial system flights into the national airspace. That's according to a new report from the Government Accountability Office. The FAA Modernization and Reform Act of 2012 directed the agency to safely integrate flights by aircraft without an onboard pilot that operate on pre-programmed routes or are remotely controlled. Gerald Dillingham is the director of physical infrastructure issues at GAO. He joined Tom Temin on the Federal Drive with more on the report and FAA's drone progress.
