U.S. Air Force and U.K. Royal Air Force personnel donate artifacts from Operation Allies Refuge to the National Museum of the U.S. Air Force at the Air Force Museum in Dayton, Ohio, July 11, 2022. The airfield signs and other items donated represent a piece of the Airmen's lives during the three and a half weeks in which the United States evacuated more than 120,000 people from Afghanistan.
