California Air National Guard airmen wave farewell (or hello) beside a Boeing C-97 Stratofreighter, duffel bags and gear in hand. Scenes like this were common at Guard airfields during the late 1950s and 1960s, as citizen-soldiers departed for annual training encampments or returned from state and federal missions. The C-97's roomy fuselage made it an ideal troop transport, ferrying Guardsmen between their home stations and training sites across the country. Project: 218665
