The first and largest of three test shots conducted at the One Tree site during operation Buffalo. A test of the Red Beard tactical bomb, the cloud to reach a height of 11,430 meters. Even though meteorological conditions were unfavourable, the shot was not postponed causing much greater fallout than expected. One noteworthy feature of the first two Buffalo explosions was the assembling of an ‘Indoctrinee Force’ designed to give British Commonwealth military personnel the opportunity to gain operational experience of the effects of nuclear weapons.
