Making the rounds on the web today is a silent film showing “the final preparation and loading of the ‘Fat Man’ bomb into ‘Bockscar,’” the plane that would drop a devastating bomb on Nagasaki on August 9, 1945. The footage from the Los Alamos National Laboratory is raw, except for the helpful annotations added by Alex Wellerstein, who runs Nuclear Secrecy: The Restricted Data Blog. Eventually, toward the 8 minute mark, the video shows “the Nagasaki explosion from the window of an observation plane.” What you don’t see is the calamitous outcome. To get a feel for the destruction, you can see our previous post, Rare Color Footage of the Hiroshima Aftermath. (Obviously Hiroshima is the other Japanese city that experienced the ruinous effects of the nuclear bomb.) Also we have 360 Degree Images of Hiroshima After the Bombing.
