One thought on “Time-lapse map of every nuclear explosion 1945 – 1998

    Trinity Test footage (9:03)
    Trinity was the code name of the first detonation of a nuclear weapon. 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.
    “Procedure for Final Assembly” by K. T. Bainbridge “The procedure used for the final assembly of the bomb is probably best given by the memorandum from N. E. Bradbury, which gives the procedure to be followed, as discussed by all members concerned, and that was evolved from the dry run.”
    Friday, 13 July, 1945 (1300) Gadget assembly starts.
    Saturday, 14 July (0800) left Gadget to top of tower. Ready for X-unit at 0900
    Note that once detonators are on sphere, no live electrical connection can be brought to x – unit, informer unit, or anywhere else on sphere. Hence all testing must be done before sphere is lifted to tower. After that it is too late.
    Gadget complete and ready for test at 1700.
    [On July 16,] “The arming party remained at the base of the tower until just before 5:00 a.m. when the weather reports from Hubbard by phone began to look satisfactory for a shot. Sgt. Stewart was released to S-10 000 before 5:00 a.m.; his job had been completed. The drive out to S-10 000 was not made above 35 mph, contrary to rumors. Original plans were for the entire party to return at 2:00 a.m. to S-10 000 where J. R. Oppenheimer, Gen. Farrell, J. M. Hubbard, and K. T. Bainbridge would decide at to-1/2 h whether or not the test should be run. One dissenting vote was sufficient to call off the shot. Sunday afternoon discussions of possible sabotage of the bomb made it reasonable for the arming party to guard the tower until the last possible moment. The final OK for the 5:30 a.m. shot was given at 5:10 a.m. because 20 min were needed for preparation in the three main shelters.”
