50 Ton Explosion 1,963
October 1, 2009
Operation Blowdown was a joint UK-US-Australian operation at Iron Range in northern Queensland, Australia 18/07/1,963. The test was conducted to simulate the effects of a small nuclear detonation over a rain forest. It involved the detonation of 50 tons of TNT atop a 43 meter tower. The explosion turned the surrounding forest into a twisted knot making troop movements almost impossible.
