Frederick C. Bock (1918 – August 25, 2000)[1] was a World War II pilot who took part in the atomic bombing of Nagasaki in 1945, flying the B-29 bomber The Great Artiste, which was used for scientific measurements of the effects caused by the nuclear weapon. The bomber which actually dropped Fat Man was called Bockscar[2] as it was usually flown by Frederick Bock. The staff was swapped just before the raid and Major Charles Sweeney piloted Bockscar, which flew with The Great Artiste and another aircraft.
