Dec 15, 2017 · There are several key things a physicist can look for in one of these videos to take measurements of the amount of energy released (known as the yield) in each explosion. One of these is the two light pulses typical of nuclear detonations, clearly seen in a video of Operation Dominic in 1962.

- Film #2: Operation Teapot—Tesla 28617

In this film, a device airdropped from about 12,000 feet above the Pacific detonates on October 30, 1962. The film shows the two characteristic light output pulses that are seen only in nuclear weapon blasts, which correlate with the device’s yield (the amount of energy given off from the explosion). The first pulse occurs when the shock wave forms...
Tesla was a relatively low-yield shot of seven kilotons, dropped from a 300-foot tower at the government’s test site in Nevada on March 1, 1955. When the shock wave hits the ground in the video, it kicks up the dry desert soil and “it makes a nice little dust cloud,” Spriggs says. After the second pulse of light reaches its maximum, the bright whit...
The Nutmeg test was detonated from a barge tethered to Bikini Atoll in the Pacific on May 21, 1958. In this film the initial blast and scattering of light are visible but high humidity obscures the fireball itself. As the shock wave travels away from the blast, it changes the atmospheric pressure and creates a low-pressure trough in its wake. Conde...
The Bighorn device was dropped over the Pacific Ocean from a height of around 12,000 feet on June 27, 1962. Thanks to the high altitude, the detonation occurs above the humid layer of the lower atmosphere. The bright light erupts from the second pulse, and then the gases start to escape. As the shock wave propagates downward, it flows through the m...
