This 1965 color snapshot captures a formation of helicopters -- likely Bell UH-1 'Huey' utility helicopters -- climbing through the skies over South Vietnam. Photographed informally, probably by a serviceman stationed near an airfield, the image reflects the rapidly escalating American air mobility campaign of the mid-1960s, when helicopter formations like this one became a defining sight of the Vietnam War, ferrying troops and supplies across the contested countryside.
