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.
Views of the nuclear test device nicknamed, "Gadget", showing network of wires going to detonators surrounding core.
