The Air Force says all six crew members aboard a B-52 bomber that crashed Monday off Guam were killed.

An announcement from Andersen Air Force Base on Guam says a wide search effort has shifted focus from rescue to recovery of the aircrew. Two bodies have been found.

The Air Force has released the name of only one crew member so far: 33-year-old Maj. Christopher Cooper of Austin, Texas.

The crew was based at Barksdale Air Force Base in Louisiana. Flags are being flown at half-staff at the Louisiana state Capitol to honor them.

The unarmed bomber was making a swing around the island as part of Guam Liberation Day celebrations marking liberation of the island from Japan in World War II.
