FIRST EXPERIMENTAL BLAST SET OFF IN NEW MEXICO; BOMBING AND DEVASTATION OF HIROSHIMA AND NAGASAKI.
'Shortly after the end of the war an American mission was sent to Japan, to report on the destruction wrought by the atomic bombs. The mission, organized by the Manhattan Engineer District, included engineer and medical officers and a few scientists. This film portrays some of the devastation they witnessed.'
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Atom Strikes is a document commissioned by the U.S. Army Signal Corps Pictoral Division shortly after the end of the Second World War. It documents the findings of a commission sent to Japan to assess the damage caused by the atomic bombing of Hiroshima and Nagasaki.
Opening with the blast of the experimental bombing in Los Alamos, New Mexico in July 1945, the film turns to the Enola Gay and its mission over the Japanese city of Hiroshima. The narrator informs the audience about the military significance of the city and that it had not experienced bombing as yet, but it had been warned. The results of the bombing are then explained, with footage and descriptions of how various buildings were affected by the blast at different distances from ground zero. Afterwards, an interview with Father John A. Siemes, a Jesuit priest who was living at the Novitiate of the Society of Jesus in Nagatsuka, is shown to give the audience a firsthand account of the bombing. Near the end of the interview, the priest is seen reading from a prepared statement.
Nagasaki is then mentioned, with the narrator pointing out how much armament and other military supplies were being produced there, as well as the fact that even civilian homes were used for war work. Nevertheless, the effect of the atomic blast on local schools and churches is also shown...
https://en.wikipedia.org/wiki/Trinity_(nuclear_test)
Trinity was the code name of the first detonation of a nuclear device. It was conducted by the United States Army at 5:29 a.m. on July 16, 1945, as part of the Manhattan Project. The test was conducted in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range, now part of White Sands Missile Range. The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test.
The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne. The test was of an implosion-design plutonium device, informally nicknamed "The Gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. The complexity of the design required a major effort from the Los Alamos Laboratory, and concerns about whether it would work led to a decision to conduct the first nuclear test. The test was planned and directed by Kenneth Bainbridge.
Fears of a fizzle led to the construction of a steel containment vessel called Jumbo that could contain the plutonium, allowing it to be recovered, but Jumbo was not used. A rehearsal was held on May 7, 1945, in which 108 short tons (96 long tons; 98 t) of high explosive spiked with radioactive isotopes were detonated. The Gadget's detonation released the explosive energy of about 22 kilotons of TNT (92 TJ). Observers included Vannevar Bush, James Chadwick, James Conant, Thomas Farrell, Enrico Fermi, Richard Feynman, Leslie Groves, Robert Oppenheimer, Geoffrey Taylor, Richard Tolman and John von Neumann.
The test site was declared a National Historic Landmark district in 1965, and listed on the National Register of Historic Places the following year...
