Vietnam War: Operation Frequent Wind: The U.S. begins to evacuate U.S. citizens from Saigon before an expected North Vietnamese takeover. U.S. involvement in the war comes to an end. This happens after the Bombing of Tan Son Nhut Air Base.

Operation Frequent Wind was the final phase in the evacuation of American civilians and "at-risk" Vietnamese from Saigon, South Vietnam, before the takeover of the city by the North Vietnamese People's Army of Vietnam (PAVN) in the Fall of Saigon. It was carried out on 29–30 April 1975, during the last days of the Vietnam War. More than 7,000 people were evacuated by helicopter from various points in Saigon. The airlift resulted in several enduring images.

Ho Chi Minh City, also known as Saigon, is the most populous city in Vietnam with a population of 14,002,598 in 2025.

North Vietnam, officially the Democratic Republic of Vietnam, was a country in Southeast Asia from 1945 to 1976, with sovereignty fully recognized in 1954. A member of the communist Eastern Bloc, it opposed the French-supported State of Vietnam and later the Western-allied Republic of Vietnam. The DRV invaded Saigon in 1975 and ceased to exist the following year when it merged with the south to become the current Socialist Republic of Vietnam.

The Bombing of Tan Son Nhut Air Base occurred on 28 April 1975, just two days before the Fall of Saigon. The bombing operation was carried out by the Vietnam People's Air Force (VPAF) Quyet Thang Squadron, using captured Republic of Vietnam Air Force (RVNAF) A-37 Dragonfly aircraft flown by VPAF pilots and RVNAF defectors led by Nguyen Thanh Trung who had bombed the Presidential Palace in Saigon on 8 April 1975.
