SEYMOUR JOHNSON AIR FORCE BASE, N.C. -- On a quarterly basis, members of the 916th Air Refueling Wing walk the KC-135 ramp in search of debris that could potentially damage aircraft. The debris, otherwise known as FOD (Foreign Object Damage), can be anything from rocks to loose cement to a wide array of other items. Reservists and civilians from the Air Force Reserve wing participated in the quarterly walk this week prior to the unit training assembly weekend. U.S. Air Force photo/Ms. Donna Lea
