On 9 August 1945, the United States dropped an atomic bomb on Nagasaki, Japan, killing at least 74,000 people.
It led to the end of World War Two in Asia, with Japan surrendering to the Allies six days later.
The Nagasaki bomb, alongside the Hiroshima bomb on 6 August, remain the only times nuclear weapons have been used in a war.
In an interview he gave to the BBC in 1980, British prisoner of war Geoff Sherring describes how he survived the explosion. Produced and presented by Rachel Naylor.
