The temperature of the ground beneath the burst reached an estimated 3,000 to 4,000 degrees Centigrade and the heat rays caused flash burns up to 13,000 feet away. In a millisecond, a force of 20,000 tons of TNT was released, generating a fireball of heat equivalent to 300,000 degrees Fahrenheit.
The Little Boy uranium bomb fell from 31,600 feet, detonating 43 seconds later, 600 yards in the air over the city.

The crew put on the dark goggles and turned on the tone for the instrument plane to know exactly when the bomb was released. Ferebee checked the bomb sights and said “I have the aiming point in sight.” Van Kirk checked and agreed. Col Tibbets described the final minutes before the drop: We made the final turn to 272 degrees magnetic course for 14 minutes (72 NM). The two other 509th planes that accompanied the Enola Gay included the instrument aircraft, the Great Artiste, piloted by Major Charles Sweeney and a third B-29, equipped with photographic equipment, commanded by Major George Marquardt.Īs the crew approached the mainland of Japan, the weather was clear for the visual drop requirement.
