The sky was as clear as it had bee on August 6, 1945, when, at 08:15 local time the American bomber B-29 Enola Gay dropped the nuclear bomb known as ‘Little Boy’ from the altitude of 9.600 meters. It exploded 43 seconds later, 600 meters above the ground. On that day and a few weeks after an estimated 140.000 people died.
