This silent film shows the final preparation and loading of the "Fat Man" bomb into "Bockscar," the plane which dropped the bomb on Nagasaki. It then shows the Nagasaki explosion from the window of an observation plane. This footage comes from Los Alamos National Laboratory. I have not edited it in any way from what they gave me except to improve the contrast a little — it is basically "raw."
