where did the atomic bomb drop on hiroshima
Atomic bombings of Hiroshima and Nagasaki Due to crosswind, the bomb missed the aiming point, the Aioi Bridge, by approximately 800 ft (240 m) and detonated directly over Shima Surgical Clinic.[139] It released the equivalent energy of 16 kilotons of TNT (67 TJ), ± 2 kt.[136] The weapon was considered very inefficient, with only 1.7% of its material fissioning.[140] The radius of total destruction was about 1 mile (1.6 km), with resulting fires across 4.4 square miles (11 km2).[141]
