Chaplain Candidates visit Barksdale
Staff Sgt. Steven O’Brien, a firefighter assigned to the 2nd Civil Engineer Squadron, receives a thumbs-up sign from Chaplain Candidate 2nd Lt. Daniel Fairchild at the top of Ladder 21 on Barksdale Air Force Base, La., July 31, 2012. The thumbs up signals that radio communications have been established between the two Airmen, or that Fairchild is “locked in, safe and good to go.” (U.S. Air Force photo by Master Sgt. Jeff Walston)
