DENVER — The remains of an Air Force officer who had been missing in action in southeast Asia during the Vietnam War have been recovered and buried.

Maj. Thomas B. Mitchell graduated from the Air Force Academy in 1963 and was among nine U.S. airmen aboard a C-130 over Laos on May 22, 1968, that lost radio contact.

The crew of another aircraft saw a large ground fire near the last known location of the cargo plane, but heavy anti-aircraft fire kept search and rescue aircraft away.

Search teams from the U.S., Vietnam and Laos found the remains and personal items after searches between 1989 and 2008.

Individually identifiable remains were returned to their families for burial. Other remains were buried last week in Arlington National Cemetery.

DAYTON, Ohio — Wright-Patterson Air Force Base near Dayton is changing policy and allowing employees to access social networking websites from base computers.

Officials on Monday began allowing access to 29 of the most popular sites including Facebook, Twitter and YouTube. Access to 40 additional websites will be permitted in the coming weeks.

Col. Michael Stinson, commander of the 88th Communications Group, is reminding airmen to be wary of how much information they volunteer. He says security could be jeopardized if base users disclose key information.

Air Force officials say personal use of social websites must be of reasonable duration and must not interfere with official duties or overburden military computer networks.
