What time they bomb Hiroshima in the WW2?

Answer 1

At 08:15 (Hiroshima time), the Enola Gay dropped the nuclear bomb called "Little Boy" over the center of Hiroshima. It exploded about 600 meters (2,000 ft) above the city with a blast equivalent to about 13 kilotons of TNT (the U-235 weapon was considered very inefficient, with only 1.38% of its material fissioning),[15] instantly killing at least an estimated 90,000 people.[16] Of this number, there were approximately 2,000 Japanese Americans who died from the blast and another 800-1,000 who lived on as hibakusha. As U.S. citizens, many of these Japanese Americans were attending school before the war and had been unable to leave Japan. It is likely that hundreds of Allied prisoners of war also died. The radius of total destruction was about 1.6 km (1 mile), with resulting fires across 11.4 square km (4.4 square miles). Infrastructure damage was estimated at 90% of Hiroshima's buildings being either damaged or completely destroyed.
