On 8 April 1975, Nguyễn Thanh Trung, a pilot of the South Vietnamese air force and an undetected communist spy, flew an F-5E aircraft from Biên Hòa Air Base to bomb the palace, but caused no significant damage. At 10:45 on 30 April 1975, a tank of the North Vietnamese army bulldozed through the main gate, effectively ending the Vietnam War.
