A Naval drone aircraft crashed on Maryland's Eastern Shore on Monday without injuries or property damage on the ground, officials said.
The 44-foot (13.4-meter) plane on a routine training flight crashed around noon near Bloodsworth Island, across the Chesapeake Bay from the Patuxent River Naval Air Station, according to Jaime Cosgrove, a spokeswoman for the Unmanned Aviation and Strike Weapons program.
Aerial video from WBOC-TV showed a plane-shaped indentation surrounded by burning debris at the swampy crash site.
The cause is being investigated and the U.S. Coast Guard has set up a safety zone around the crash site, officials said.
The Northrop Grumman RQ-4A BAMS-D drones with a range of 10,500 nautical miles can reach 11 miles (17.7 kilometers) above the ground, which is above most weather, and stay in the air for more than 30 hours with speeds up to 391 mph (629 kph), according to the Navy. It is operated by a crew of four on the ground.
The aircraft is one of five acquired from the Air Force Global Hawk program that support more than half of maritime intelligence, surveillance and reconnaissance systems. They have flown more than 5,500 hours in support of combat operations since 2008.
