More than 1,700 people, many of whom were dressed in the US Air Force's dark blue service dress uniform, filled the lower and upper levels of the Rose State College Performing Arts Center Monday morning, May, 13, 2013, to attend a memorial service for SSgt. Daniel N. Fannin, a brother in arms killed April 27 in a plane crash while on a mission in Afghanistan. Fannin , 30, was assigned to the 552nd Operations Support Squadron at Tinker Air Force base.
