Bockscar
Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second – and last – nuclear attack in history. One of 15 Silverplate B-29s used by the 509th, "Bockscar" was built at the Glenn L. Martin Aircraft Plant at Bellevue, Nebraska, at what is now Offutt Air Force Base, and delivered to the United States Army Air Forces on 19 March 1945. It was assigned to the 393d Bombardment Squadron, 509th Composite Group to Wendover Army Air Field, Utah in April.
