Maj. Christopher Cooper of Massena, N.Y., was aboard the bomber when it crashed into the Pacific Ocean, the Daily Courier Observer and WNYF-TV said.

Col. George Martin, an Air Force doctor, is the other airman aboard the plane to be identified by a family member. 

Four airmen are missing and feared dead. Two bodies from the six-member crew were found after the crash.

"Although we continue to hold out hope, we've had no encouraging indications that our airmen survived this crash," said Brig. Gen. Douglas Owens of Andersen Air Force Base on Guam.

No names of the plane's crew have been released by the Air Force.

Flags at municipal buildings in Bossier City will be flown at half staff through Friday in recognition of the B-52 crew.

"Our hearts are heavy from this tragic loss," said Bossier City Mayor Lorenz Walker, a retired Air Force colonel. Our prayers go out to the families of the lost crew members and to the Barksdale community."

Gov. Bobby Jindal has ordered flags lowered to half staff at the state Capitol and all public buildings within 10 miles of Barksdale until Aug. 11.

The B-52 was in Guam as part of the U.S. rotation of bomber crews in the Pacific.

Coast Guard Lt. John Titchen said searchers have seen fuel in the water and what looks like plane debris. They are now adding wind and water current as factors for the search area.

The unarmed Air Force bomber had been on a training mission and was making a swing around the island from Andersen Air Force Base for a celebratory fly-over of another part of the island, the Air Force said. It was to be part of Guam Liberation Day celebrations, marking the day the U.S. military arrived to retake the island from Japan during World War II.
