Martin Guardado Dr. Long English 350 03/02/15 The Demolition in 9/11 On 9/11 two passenger planes struck The Twin Towers of The World Trade Center, and moments later the two buildings collapsed. It appears that the reason behind the collapse was because of the impact of the plane and the fire that followed. To others, such as some survivors, non-governmental researchers, engineers, and scientists that have studied or witnessed the collapse, it appears as a demolition. Despite the reasons for the collapse of the twin towers and building 7 on the official report of 9/11 by the government and the authority figures associated with it, other non-government figures such as researchers, engineers, scientist and surviving witnesses provide a clearer explanation on what caused the buildings to collapse. On the official report of 9/11 it says that the collapse happened because of the fire in the buildings, but regardless other evidence contradicts this theory.
That would have meant that fifteen thousand more men would have been taken away from their families. That is one of the many pros for the dropping of the atom bombs. This is one of the cons for the atomic bombing on Hiroshima and Nagasaki. Because of the atom bombs being dropped on Hiroshima and Nagasaki millions of people were killed, and the radiation led illness, birth defects, and death. When the atom bombs were dropped most of the cities in the radius of the blast were leveled.
Researchers say they know how the Hindenburg airship came to its fiery end: static electricity. Seventy-six years ago, the German dirigible was promoted as the future of trans-Atlantic flight, but instead it became the notorious poster child of air disasters. As the hydrogen-filled blimp was landing in Lakehurst, N.J., on May 6, 1937, it suddenly burst into flames and crashed in front of shocked bystanders, killing 35 of the 100 passengers and crew on board—and putting an end to the short-lived air travel program. Now scientists who have been studying the circumstances that led to the Hindenburg’s end say they know what happened. The Independent, in an article about a documentary on the Hindenburg airing on Britain's Channel 4 on Thursday, explains that Jem Stansfield, a British aeronautical engineer who led a team of researchers at the Southwest Research Institute in San Antonio, Texas, blew up and set fire to models of the dirigible to rule out possibilities including a bomb and exploding paint.
Andrew Tull Hiroshima On August 6, 1945, the United States dropped the equivalent of 67 million sticks of dynamite on the heavily militarized city of Hiroshima, Japan. Earlier that year, in the month of July, Robert Oppenheimer directed the scientific campaign of creating and testing the bomb. All information about the bomb was top secret. It was so top secret that President Truman was not even told about it until after he took office. The airmen that dropped such a force of destruction did not know much about it either.
A year ago on the date of September 2011 in Reno, Nevada there was an air racing disaster that occurred. This disaster involved the death of a pilot and 10 others. It also injured 70 people. Thorough investigations and inspections have taken place since the crash. Two reports have noted that there was a loose screw in the tail of the airplane and that turbulence from the airplane racing close by added to the collision.
1994,When Technology Fails : significant technological disasters, accidents, and failures of the twentieth century, Gale Research, Detroit, pp.81-86. This article assesses the causes and consequences of accident of United Airlines Boeing 747 Hawaii (1989). The authors enlighten two other accidents which were connected severely with this accident which are Pan Am 747-100(1987) and Kennedy International Airport 747-200 (1991) . Schlager, Neil (ed.) 1994 conclude that the real causes of this disaster were weak locks of the door and the stray signals produced by some pair of wires which made the opened itself without any command.
I wasn't sure at first either, but after some research for a class, I found that the bombings were unnecessary. By June 1945, Japan had already been militarily defeated. Almost nothing was left of Japan's navy, and its air force was almost totally destroyed. The explosions destroyed more than four square miles of Hiroshima. About 90,000 people were killed immediately, and another 40,000 were injured (many of whom died from radiation sickness.)
Three days later, another atom bomb was dropped on Nagasaki. It is estimated that between 150,000 and 250,000 people were killed as a result of the bombings. However, once the Japanese government witnessed the destructive power of the bombs, they had no choice but to surrender. Had the bombs not been used, the war would have gone on for much longer.
Response to 9/11 The Event On 11th September 2001, four planes were hijacked by Al-Qaeda. One of the planes flew into the North Tower of the World Trade Centre in New York City. 20 minutes after this horrible event, with camera crews sending pictures all over the world, a second plane crashed into the South Tower. Both Towers collapsed, killing 2,752 people. This number includes the innocent people on the planes, firemen, policemen and medical staff who had all gone to assist the crisis.
The flight departed JFK about 2019, with 2 pilots, 2 flight engineers, 14 flight attendants, and 212 passengers on board. All 230 people on board were killed. Cause of Accident The National Transportation Safety Board determines that the probable cause of the TWA flight 800 accident was an explosion of the center wing fuel tank (CWT), resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but, of the sources evaluated by the investigation, the most likely was a short circuit outside of the CWT that allowed excessive voltage to enter it through electrical wiring associated with the fuel quantity indication system. Contributing Factors The design and certification concept that fuel tank explosions could be prevented solely by precluding all ignition sources, the certification of the Boeing 747 with the heat sources located beneath the CWT with no means to reduce the heat transferred into the CWT or to render the fuel vapour in the tank non-flammable, the cracked insulation of the FQIS wiring due to maintenance lapses that could have caused the ignition are some of the contributing factors to the
