A second atomic bomb, Fat Man, killed 80,000 in Nagasaki three days later. VanKirk, also known as 'Dutch,' was the navigator of the Enola Gay, a B-29 Superfortress, that dropped Little Boy - the world's first atomic bomb - over the Japanese city of Hiroshima Aug. VanKirk had been the lone surviving crew member since the death of Morris Jeppson on March 30, 2010. Tom VanKirk says his father, Theodore VanKirk, 93, died Monday in Stone Mountain. The last surviving member of the crew that dropped the atomic bomb on Hiroshima has died in Georgia nearly 70 years after the bombing, which killed 140,000 people.
