A UH-1 "Huey" helicopter banks across a clear sky over South Vietnam, its cargo doors open and crew visible within. The Huey was the defining aircraft of the Vietnam War, used for troop insertions, medical evacuations, resupply, and gunship missions throughout the conflict. This image, from a slide collection documenting the 1968 Tet Offensive, reflects the intense pace of helicopter operations during one of the war's most pivotal campaigns. Project: 218418
