Sweeney, whose regular plane was The Great Artiste. However, on the day of the Nagasaki bombing, Bock switched planes with Charles W. The plane was named after Frederick Bock, the plane's commander. Adaptations included removing most of the armament installing heavier racks to support the heavy bomb and replacing the engines. Just as its counterpart the Enola Gay, the Bockscar had been altered to serve the purpose of carrying and deploying the heavy bomb. This marked only the second time in history that the atomic bomb had been used. On August 9, 1945, the Bockscar dropped an atomic bomb (the 'Fat Man') on Nagasaki, instantly killing tens of thousands of people. Captain Beahan, Captain Van Pelt, Jr., First Lt.
