Transcript of Bombing on Hiroshima and Nagasaki

The attack on Japan's two cities, Hiroshima and Nagasaki, was part of World War II. As we recalled, WWII was about Hitler assassinating Jews from his own prejudice. So how does this tie in with Japan? How did Japan get involved in the war?
Enola Gay
was the B29 bomber plane that dropped the bomb over Hiroshima, Japan.
This was the first bomb deployed over Hiroshima.
The atomic bombed wiped out 90% of the city.
80,000 Japanese civilians were estimated to have died.
10,000/more died from radiation exposure after the bomb started to settle.
A fire storm of winds followed the blast at Hiroshima as air was drawn back to the center of the burning area.
Aug. 6, 1945
3 days after Hiroshima's bombing, Nagasaki was bombed.
The B29 bomber plane,
, was used to drop the bomb over Nagasaki.
This atomic bomb was estimated to have killed 40,000 people.
Buildings collapsed, flying debris caused many injuries, electrical systems were shorted, and trees were uprooted.
A wave of secondary fires resulted, adding to their holocaust.
Flash burns from primary heat waves caused most of the damages. Other civilians were burned when their homes burst into flame.

Bombing on Hiroshima and Nagasaki
Through some extensive research we found out that Japan joined Germany and Italy in an alliance called the Axis Powers to gain more control by dominating other countries. Japan feared that the US would try to stop them from their goal, so they bombed Pearl Harbor. To get even with Japan, the US bombed Hiroshima and Nagasaki in turn.
Consider This...
Hiroshima, Japan
Nagasaki, Japan
Fat Man
Akiko Takakura
Akiko was 20 years old when the bomb fell. She was in the Bank of Hiroshima, 300 meters away from the hypocenter. Ms. Takakura miraculously escaped death despite over 100 lacerated wounds on her back. She is one of the few survivors who was within 300 meters of the hypocenter. She now runs a kindergarten and she relates her experience of the atomic bombing to children.
From this presentation, we hoped that it has touched your hearts and see the affects of war. Although what America did in return of the Japanese's attack on Pearl Harbor seem like the only way to pay back, many innocent lives were still affected.

After Effects
Both cities of Japan were in ruins and almost completely gone.
Buildings were pushed off of their foundations, gutted by fire, or utterly destroyed.
Cemeteries were uprooted, and churches had become piles of debris.
Psychologists reported increased complaints among survivors of neurotic symptoms including fatigue, amnesia, lack of concentration, and PTSD (Post Traumatic Stress Disorder).
About 90% of all medical personnel were killed or injured, and the remaining medical supplies quickly diminished.
Symptoms ranged from nausea, bleeding and loss of hair, to death.
Flash burns, a susceptibility to leukemia, cataracts, malignant tumors, keloids, and thermal burns were some of the other effects.
He was 14 years old, when the bomb was dropped. He was standing in line with other students of his junior high school, waiting for the morning meeting 1.4 km away from the center. He was under medical treatment for about year and half. And even today black nail grows at his finger tip, where a piece of glass was stuck.
"The heat was tremendous . And I felt like my body was burning all over. For my burning body the cold water of the river was as precious as the treasure. Then I left the river, and I walked along the railroad tracks in the direction of my home. On the way, I ran into an another friend of mine, Tokujiro Hatta. I wondered why the soles of his feet were badly burnt... But it was undeniable fact the soles were peeling and red muscle was exposed. Even I myself was terribly burnt, I could not go home ignoring him...When we were resting because we were so exhausted, I found my grandfather's brother and his wife, in other words, great uncle and great aunt, coming toward us...They seem to be the Buddha to me wandering in the living hell."
Eiko Taoka
Eiko, then 21, was one of nearly 100 passengers said to have been on board a streetcar that had left Hiroshima Station at a little after 8:00 a.m. and was in a Hatchobori area, 750 m from ground zero, when the bomb fell. Taoka was heading for Funairi with her one year old son to secure wagon in preparation for her move out of the building which was to be evacuated. At 8:15, as the streetcar approached Hatchobori Station, an intense flash and blast engulfed the car, instantly setting it on fire. Taoka’s son died of radiation sickness on August 28. The survival of only ten people on the streetcar have been confirmed to date.
"When we were near in Hatchobori and since I had been holding my son in my arms, the young woman in front of me said, ‘I will be getting off here. Please take this seat.’ We were just changing places when there was a strange smell and sound. It suddenly became dark and before I knew it, I had jumped outside.... I held [my son] firmly and looked down on him. He had been standing by the window and I think fragments of glass had pierced his head. His face was a mess because of the blood flowing from his head. But he looked at my face and smiled. His smile has remained glued in my memory. He did not comprehend what had happened. And so he looked at me and smiled at my face which was all bloody. I had plenty of milk which he drank all throughout that day. I think my child sucked the poison right out of my body. And soon after that he died. Yes, I think that he died for me."
"Many people on the street were killed almost instantly. The fingertips of those dead bodies caught fire and the fire gradually spread over their entire bodies from their fingers. A light gray liquid dripped down their hands, scorching their fingers. I, I was so shocked to know that fingers and bodies could be burned and deformed like that. I just couldn't believe it. It was horrible. And looking at it, it was more than painful for me to think how the fingers were burned, hands and fingers that would hold babies or turn pages, they just, they just burned away. For a few years after the A-bomb was dropped, I was terribly afraid of fire. I wasn't even able to get close to fire because all my senses remembered how fearful and horrible the fire was, how hot the blaze was, and how hard it was to breathe the hot air. It was really hard to breathe. Maybe because the fire burned all the oxygen, I don't know. I could not open my eyes enough because of the smoke, which was everywhere. Not only me but everyone felt the same. And my parts were covered with holes."
"We are on our way to bomb the mainland of Japan. Our flying contingent consists of three specially designed B-29 Superforts, and two of these carry no bombs. But our lead plane is on its way with another atomic bomb, the second in three days, concentrating its active substance, and explosive energy equivalent to 20,000, and under favorable conditions, 40,000 tons of TNT...
Does one feel any pity or compassion for the poor devils about to die? Not when one thinks of Pearl Harbor and of the death march on Bataan...
Then, just when it appeared as though the thing has settled down into a state of permanence, there came shooting out of the top a giant mushroom that increased the height of the pillar to a total of 45,000 feet. The mushroom top was even more alive than the pillar, seething and boiling in a white fury of creamy foam, sizzling upwards and then descending earthward, a thousand old faithful geysers rolled into one.
It kept struggling in an elemental fury, like a creature in the act of breaking the bonds that held it down. In a few seconds it had freed itself from its gigantic stem and floated upward with tremendous speed, its momentum carrying into the stratosphere to a height of about 60,000 feet."

William Leonard Laurence (March 7, 1888 – March 19, 1977) was a Jewish Lithuanian-born American journalist known for his science journalism writing of the 1940s and 1950s while working for The New York Times. He won two Pulitzer Prizes and, as the official historian of the Manhattan Project, was the only journalist to witness the Trinity test and the atomic bombing of Nagasaki. He is credited with coining the iconic term "Atomic Age" which became popular in the 1950s.
