You must know about Hiroshima, as B-29 bomber named Enola Gay was set off from the island of Tinian and headed north by the northwest towards Japan. It was facing the Inland Sea and was the main target of this bomber with a population of about 300,000. It was the most important center for the military which had 43,000 soldiers. This bomber was piloted by Colonel Paul Tibbets who was the commander of the 509th Composite Group. He was flying on his automatic pilot at a low altitude before he climbed the 31,000 ft as it was going near to the target area.
The Hiroshima Explosion:
At Hiroshima time of 8:15 am the Enola Gay released the “Little Boy.” It was its 9,700-pound uranium gun-type bomb over the city. The Tibbets went away from the place to avoid the expected shock wave. After just 43 seconds, a huge explosion lit in the sky as the Little Boy exploded 1,900 ft above the city. This bomber fell directly over the parade field, where the Japanese Second Army soldiers were practicing. Though it was eleven and a half-mile away, the Enola Gay was shaken by the blast.
People thought it was flak until the second wave hit the plane and the crew looked at the City of Hiroshima. All they could see was the city covered by the awful cloud, that was boiling, it was terrible and extremely tall. The explosion was approximately 15 kilotons which are equal to 15,000 tons of TNT.
What Happened Before This
Before the blast, the ground moment was calm and sunny. The air attack alert was called in the morning on sight, a solitary aircraft. The soldiers were practicing, and commuters were on their foot or their bicycles, women, and children doing their work. Those people who were near the explosion died on the spot as their bodies turned into black char. The birds that were near also burst into flames in the middle of the air. Materials like paper ignited on the spot even when they were far as 6,400 ft from the ground zero. The white light was like a giant flashback. It burned the dark patterns of the clothing on the bodies and the shadows on the walls.
The survivors who were outdoors are close to the blast. They described it as a blind light that was combined with a sudden heatwave. The wave of the blast followed immediately for those who were close to the spot and it knocked them from their feet. Those people who were indoors spared the burns. The room was filled with flying glass from the windows, and the strongest structures of the city also collapsed. One boy was blown out of the window on the streets as the house collapsed. Just within a minute, those who were a mile or less away from the ground, 9 out of 10 died. Those who were far from the explosion point first witnessed the flash and then the heat.
