Hiroshima was the primary target of the first nuclear bombing mission on 6 August, with Kokura and Nagasaki as alternative targets. Enola Gay, piloted by Tibbets, took off from North Field, in the Mariana Islands, about six hours ' flight time from Japan, accompanied by two other B - 29s, The Great Artiste, carrying instrumentation, and a then - nameless aircraft later called Necessary Evil, commanded by Captain George Marquardt, to take photographs. The director of the Manhattan Project, Major General Leslie R. Groves, Jr., wanted the event recorded for posterity, so the takeoff was illuminated by floodlights. When he wanted to taxi, Tibbets leaned out the window to direct the bystanders out of the way. On request, he gave a friendly wave for the cameras.
