Explosion of the first ever Atomic Bomb at Alamogordo, New Mexico in World War II. Brilliant flash at detonation of the Atomic bomb. Huge smoke cloud rises. Smoke all around. Narrator indicates that men 5 miles away were knocked down, that a pressure wave was felt and the sound and quake was noted in an area 300 square miles in size. He indicates that the testing platform was vaporized. He comments on the awesome power of the weapon, its ability to shorten the war, and the important responsibility that rests with those who know the secrets of the weapon.
Activities the day before the Trinity nuclear test conducted at Alamogordo in New Mexico during World War II (part of the Manhattan Project). Technicians and physicists work inside a tent erected on the test tower platform in the Jornado del Muerto desert test site. The men perform final arming of the plutonium core nuclear implosion device nicknamed the "Gadget". White duct tape seen in use in places on and in the enclosure; as a adhesive since welding would be prohibitive. They attach the Gadget, the first atomic bomb in history, to a crane hook. Persons seen in the footage include Herbert Lehr and Louis Slotin. Also seen is Robert Oppenheimer at 0:38-0:40 wearing a soft brimmed hat, shirtsleeves rolled up to elbows, and ID badge at center of chest. Oppenheimer is seen again, no longer wearing hat (now holding it in his right hand), in blue collared shirt, standing behind the device from 1:13 to end of clip.
Activities prior to the Trinity nuclear test conducted at Alamogordo in New Mexico during World War II. This is the day before the first ever atomic bomb test in history (the first ever detonation of a nuclear device). The plutonium core nuclear device nicknamed the "Gadget" being raised up to the top of the steel tower after final assembly. Men arrange drum shaped cushioning pads on platform, under the device, as the hoisting begins, and cover the pads with canvas tarps. The Gadget atomic bomb being hoisted to the top of a 20 meter steel tower for detonation early the next morning.
The first detonation of a nuclear device in history. Trinity nuclear test being conducted at Alamogordo in New Mexico during World War II. Pitch black night is blindingly illuminated as the nuclear device sometimes nicknamed "The Gadget" is detonated in the White Sands Proving Ground, ushering in the "atomic age." Then the mushroom cloud of the atomic bomb explosion can be seen. Billowing smoke and fire fills the view.

View of the Oak Ridge Tennessee bomb fabrication plant and various other buildings of Y-12 complex involved in the Manhattan Project. Post Office erected for employees in the Oak Ridge community. Men and women scientists and war worders enter the plant, passing after security check. A citizen looks at a Knoxville Courier newspaper headline about the atomic bomb drops in Japan, seen on the bulletin board.
