A CH-46 Sea Knight and MV-22 Osprey begin their landing during the Aug. 1,2015, CH-46 Retirement Ceremony at the Smithsonian Institution National Air and Space Museum. The retirement of the CH-46 gave DLA the opportunity to find new life for the shelters that housed the simulators for the outdated aircraft as new homes for simulators that support the new MV-22.
