Nguyễn Cao Kỳ ( listen; 8 September 1930 – 23 July 2011) served as the chief of the Vietnam Air Force in the 1960s, before leading the nation as the prime minister of South Vietnam in a military junta from 1965 to 67. Then, until his retirement from politics in 1971, he served as vice president to bitter rival General Nguyễn Văn Thiệu, in a nominally civilian administration.
