Excerpt from the documentary film of the first British atomic bomb test.

This clip, from a documentary made by Anvil Films for the British Ministry of Supply, is about Operation Hurricane -- the first British atomic bomb test, conducted in the Montebello Islands 100 kilometres off the north-western coast of Western Australia in October 1952. The clip begins inside British workshops where monitoring instruments, explosion-measuring devices, documentation equipment and parts of the bomb are manufactured and tested. The final stages and countdown, including the bomb's detonation and explosion, are recorded on the island in both colour and black and white.
