0800042 - Atomic Blasts- Operations Greenhouse Through Upshot-Knothole - 1951-1953 - 29:22 - Color - Silent - This video shows a compilation of early atomic blasts taken from individual short films of the tests. These formerly classified films have never before been seen by the public. The video shows close up footage of boiling, tumbling, rolling fireballs of great destructive force as the nuclear power from the splitting of nuclei of atoms is unleashed. The blinding fury released by these early atomic devices demonstrates the show of power that was used by the United States to end World War II and establish a power base for the Cold War to follow. The term "atomic" designated them as fission devices, as opposed to the later much more powerful thermonuclear devices, which used a fission test to start a fusion process. Eventually, the word "atomic" was replaced by the term "nuclear." By the time Operation Greenhouse was conducted, the Atomic Energy Commission began testing devices of higher yields than those detonated in the TRINITY test or in Operations Crossroads, Sandstone or Ranger. Laboratory scientists were using the data gained from the early operations to build more sophisticated devices that delivered more power. The three "atomic" tests in four-test Greenhouse Operation (DOG, EASY, and ITEM) had respective yields of 81, 47 and 45.5 kilotons (kt) compared with the 21 kt yield of the earlier devices of the Fat Man (ie, TRINITY) design. These tests, fired from 300 ...
