More than 57 boxes are filled with toys, clothes, first aid kits, food and supplies Dec. 4 at Andersen Air Force Base, Guam, during the Operation Christmas Drop box build. Christmas Drop is the longest running humanitarian campaign in the world marking more than five decades in operation. The concept of Operation Christmas Drop began in 1952 when locals on the island of Kapingamarangi waved to the crew of a WB-50 flying overhead. In the spirit of the holiday season, the crew gathered what they could, packed it into a canister, attached a parachute and dropped it to the islanders.
