Tibbets and his crew looked back to behold an ominous mushroom-shaped cloud boiling into the upper atmosphere. A blast of blinding light engulfed the crew as the plane made a radical turn to escape the explosion. At 8:16 the bomb was released and detonated a few thousand feet above ground. The Enola Gay arrived over the city at 7:25 a.m. The remainder of the trip to their target was unmarred by any Japanese opposition as the bomb was armed and prepared for release. Their objective was a city of approximately 350,000 located on the southwestern portion of Japan's largest island and as yet untouched by the massive bombing raids carried on by US forces.
