what happened to the twin towers in new york
September 11 attacks Four passenger airliners operated by two major U.S. passenger air carriers (United Airlines and American Airlines)—all of which departed from airports in the northeastern part of the United States bound for California—were hijacked by 19 al-Qaeda terrorists. Two of the planes, American Airlines Flight 11 and United Airlines Flight 175, were crashed into the North and South towers, respectively, of the World Trade Center complex in Lower Manhattan. Within an hour and 42 minutes, both 110-story towers collapsed. Debris and the resulting fires caused partial or complete collapse of all other buildings in the World Trade Center complex, including the 47-story 7 World Trade Center tower, as well as significant damage to ten other large surrounding structures. A third plane, American Airlines Flight 77, was crashed into the Pentagon (the headquarters of the United States Department of Defense) in Arlington County, Virginia, which led to a partial collapse of the building's west side. The fourth plane, United Airlines Flight 93, was initially flown toward Washington, D.C., but crashed into a field in Stonycreek Township near Shanksville, Pennsylvania, after its passengers thwarted the hijackers. 9/11 was the single deadliest incident for firefighters and law enforcement officers[4] in the history of the United States, with 343 and 72 killed, respectively.
Marriott World Trade Center The Marriott World Trade Center was a 22-story[1] steel-framed hotel building with 825 rooms. It opened in July 1981 as the Vista International Hotel and was located at 3 World Trade Center in Manhattan, New York City, with the World Trade Center complex having its own zip code of 10048. The hotel no longer operates and was destroyed beyond repair as a result of the terrorist attacks of September 11, 2001, after the collapse of the Twin Towers. The hotel will not be replaced as part of the new World Trade Center complex, but will rather share its name with the new office tower.
