Black Hawk helicopter crashes off Florida, 11 service members missing

Seven Marines and four soldiers aboard an Army helicopter that crashed last night in northern Florida are presumed dead, according to a Pentagon official.

Seven Marines and four soldiers aboard an Army helicopter that crashed over waters off Florida during a routine night training mission were presumed dead Wednesday as fog hampered crews' search efforts, a military official said.

The Pentagon official said all 11 service members were presumed dead and that the Coast Guard found debris in the water. The official spoke to The Associated Press on condition of anonymity because the official wasn't authorized to speak on the record.

The helicopter — a UH-60 Black Hawk from the Army National Guard — was reported missing around 8:30 p.m. Tuesday, and search-and-rescue crews found debris around 2 a.m., said Andy Bourland, spokesman for Eglin Air Force Base, outside Pensacola.

"At this time all are missing," Bourland said.

Dense fog created low visibility early Wednesday even as the sun came up, and the area was under a fog advisory. But it was unclear what conditions were like at the time of the crash.

Local law enforcement agencies vehicles were gathering Wednesday at the crash scene, near a remote swath of beach between Pensacola and Destin. The beach is owned by the military and is used for test missions.

Base officials said the Marines are part of a Camp Lejeune, North Carolina-based special operations group. The soldiers were from a Hammond, Louisiana-based National Guard unit. Names of those involved were not immediately released, pending notification of next of kin, Bourland said.

Bourland said the Army helicopter took off from a nearby airport in Destin and joined other aircraft in the training exercise.

The training area includes 20 miles of pristine beachfront that has been under the control of the military since before World War II. Military police keep a close watch on the area and have been known to run off private vendors who rent jet skis or paddle boards without permission.

Test range manager Glenn Barndollar told The Associated Press in August that the beach provides an ideal training area for special operations units from all branches of the military to practice over the water, on the beach and in the bay.

The military sometimes drops trainees over the water using boats or helicopters and the trainees must make their way onshore.
