Airmen from the 36th Airlift Squadron, Yokota Air Base, Japan, watch as the parachute deploys and a box of humanitarian goods travels to the Yap Islands below during Operation Christmas Drop, Dec. 14. Operation Christmas Drop is the Air Force’s longest-running humanitarian which began in 1952. What started as a WB-50 aircrew returning to Guam on its final flight before Christmas has turned into the longest running humanitarian campaign in the history of the U.S. Air Force and the entire world.
