The terrible tragedy of 11 September 2001 claimed the lives of a large number of people. 2973 people were killed, and this, you see, is a significant figure. The terrorist act was preceded by the seizure of four aircraft heading to California and the Eastern part of the United States. Aircraft tanks were full, so we can say that they have become guided missiles. What happened on this terrible day? On September 11, the twin towers collapsed. At 8: 45 in the North tower crashed one of the aircraft - "Boeing-767". 92 people were on Board (11 crew members, 5 terrorists and 76 passengers). The plane crashed into the gap between the 93rd and 99th floors. The fuel in the tank raged like a pillar of fire down the Elevator shaft, killing even the people in the foyer. At 10: 29 the burning building collapsed, having buried together with itself a huge number of people. The number of the plane that crashed into the twin towers is AA11. At 9: 03 in the South tower also crashed the plane, it was the second "Boeing-767". The blow fell on the interval between the 77th and 81st floors. On Board the aircraft were 65 people (5 terrorists, 9 crew members and 54 passengers). At 9:59 local time, the burning building collapsed. The number of the plane UA175. There were two more planes. One of them hit the Pentagon at 9:40. 184 people were killed. And the last one fell in a Pennsylvania forest near Pittsburgh. I was able to see the records from the so-called "black box". It became clear that the terrorists dived down when resisting passengers tried to break into the cockpit. There were 44 people on Board. According to journalists, some passengers were able to call their relatives from the captured aircraft. People reported about the terrorists: on one side 4 on other-5. There is an opinion that these data were specially fabricated by FBI because there was one call which caused big mistrust. The mother's son called and when she picked up the phone, said, "Mother, it's me, John Smith." Agree, it is unlikely that he actually started the conversation with the presentation of his name. Not a single person on Board could survive. Killed 274 people on Board the aircraft (terrorists are not counted), 2602 people in new York (and on the ground, and in the towers), 125 people in the Pentagon. Not only the twin towers were damaged. Another five buildings were either destroyed or badly damaged. In total 25 buildings suffered, and 7 had to be demolished. What are the consequences of this terrible tragedy? Two skyscrapers and the wing of the Pentagon was destroyed. About three thousand people died. The new York stock exchange suspended its operations for two days. The area adjacent to the scene of the tragedy was completely covered with ash. The President declared martial law. The terrorist attack was the beginning of the us war with Afghanistan, and then with Iraq. The tragedy received the status of a national, and the news of it flew across the world in a matter of seconds. No wonder the terrorists chose these buildings, because the twin towers were the pride of the United States. The towers were built in the 60s, at this time the prestige of America was shaken. It was decided to build something huge, grandiose, stunning to return to people optimism and belief in themselves and the future. No one imagined that the" project of the century "would turn into the main"tragedy of the century".
