Trinity Test Site, Manhattan Project,1945

The Gadget was hoisted to the top of a 100 foot steel tower. The height would give a better indication of how the weapon would behave when dropped from a bomber, as detonation in the air would maximize the amount of energy applied directly to the target (as the explosion expanded in a spherical shape) and would generate less nuclear fallout. The tower stood on four legs that went 20 feet into the ground, with concrete footings. Atop it was an oak platform, and a shack made of corrugated iron that was open on the western side. The Gadget was hauled up with an electric winch. A truckload of mattresses was placed underneath in case the cable broke and the Gadget fell. The seven man arming party, consisting of Bainbridge, Kistiakowsky, Joseph McKibben and four soldiers including Lieutenant Bush, drove out to the tower to perform the final arming shortly after 22:00 on July 15. The Manhattan Project was a research and development program by the US with the UK and Canada that produced the first atomic bomb during WWII.
