Norris Jernigan's Interview

Norris Jernigan served in the 509th Composite Group at Wendover, UT, and Tinian Island during the Manhattan Project. In this interview, Jernigan describes being assigned to the Intelligence Office of the 393rd Bomb Squadron. As a clerk, he prepared information for briefing missions and typed subsequent reports. He recalls his surprise at being transferred to Wendover and learning that the 393rd had been selected to be part of a top-secret project. Jernigan discusses what it was like serving on Tinian, the relationships between the different squadrons, and the atmosphere of the island during and between the atomic bombings of Japan. He remembers the intense secrecy surrounding the work at Wendover, the friendships he made, and the shock of spending time in sunny Cuba for training after the cold Utah winter.
