BLACKSBURG, Va. (AP) - State and federal leaders are visiting Virginia Tech to discuss research being done on unmanned aircraft systems.

Officials say Federal Aviation Administration Administrator Michael Huerta and Virginia Gov. Terry McAuliffe are scheduled to visit the Blacksburg campus Wednesday.

The visit will include a demonstration of a six-rotor, unmanned aircraft gathering information at a mock auto accident scene.

Last year, Virginia Tech was selected by the FAA as a research site for unmanned aircraft systems.

Led by Virginia Tech, the mid-Atlantic-based component of the national effort will also involve the University of Maryland and Rutgers University in New Jersey.

The research will help guide the agency as it works to introduce commercial versions of the unmanned aircraft into busy U.S. airspace.
