An Air Force carry team carries the casket with the remains of Air Force Col. Joseph Christiano, Col. Derrell B. Jeffords, Lt. Col. Dennis L. Eilers, Chieft Master Sgt. William K. Colwell, Chief Master Sgt. Arden K. Hassenger and Chief Master Sgt. Larry C. Thornton, during a burial service at Arlington National Cemetery Arlington, Va., Monday, July 9, 2012. It was Christmas Eve 1965 when the Air Force plane nicknamed "Spooky" took off from Vietnam for a combat mission. The crew sent out a "mayday" signal while flying over Laos, and after that, all contact was lost. Two days of searches turned up nothing. (AP Photo/Haraz N. Ghanbari)
