Tibbets and his copilot (Robert Lewis) looked down through the Enola Gay’s greenhouse nose at the familiar coastal contours and islands of the Inland Sea. It was a bright, clear morning, with only sparse and scattered cloud cover. They flew directly over the lobster-shaped island of Etajima, site of the Japanese Naval Academy. The port and city of Kure passed below and to their right. Ahead, the densely populated fan-shaped delta of Hiroshima came into view.
