Hiroshima Log of the Enola Gay

On August 6, 1945, seven B-29s are given their final briefing on the Hiroshima Mission. The strike plane carrying the Little Boy Atomic Bomb is Enola Gay, which is piloted by Col. Paul Tibbets and Capt. Robert A. Lewis. There are ten other men on board, including Capt. Theodore “Dutch” Van Kirk, who was the navigator. His job was to record the flight path of Enola Gay in this log, which was provided to the Atomic Heritage Foundation by Clay Perkins. This document begins on 2:55am when Enola Gay takes off and ends on 2:58pm when they landed back at the base in Tinian Island. All time is recorded in Tinian time; the time in Hiroshima is one hour earlier. Below are selections from Van Kirk’s log.
