Drone Crashes and Burns in Maryland

Washington (CNN) -- A U.S. Navy drone crashed Monday in a marsh near Salisbury, Maryland.

The RQ-4A Global Hawk drone crashed during a routine training flight from Naval Air Station Patuxent River, according to Jamie Cosgrove, a spokeswoman for the Unmanned Aviation and Strike Weapons Program at the base.

There were no injuries to civilians and no property damage, said the Navy, which said it is investigating the cause.

Video from CNN affiliate WBOC showed smoke rising from brush fires in the unpopulated area.

The drone crashed into a tributary of the Nanticoke River, a U.S. Coast Guard official said. The crash site has been blocked to recreational boat traffic while the agency investigates, the Coast Guard official said.

As soon as Navy personnel lost contact with the unmanned vehicle, a piloted aircraft was dispatched to Maryland's Eastern Shore, where it came upon the wreckage and determined that it was unlikely anyone on the ground had been hurt, Navy officials told CNN.

The crash occurred at about 12:11 p.m., near Bloodworth Island in Dorchester County, the Navy said.
