On September 11 2001 four planes were hijacked and crashed into different buildings. These are called the 9/11 attacks. The 9/11 attacks on America were attacks by a terrorist group called al-Qaeda. On September 11, 2001, 19 al-Qaeda terrorists hijacked 4 different airplanes that all took off from the east coast and were heading west. According to history.com, they chose flights going from the east coast to the west coast because the planes had a lot of fuel on them. The hijackers easily smuggled box-cutters and knives through security at the airports. One of the planes was crashed into World Trade Center 1. Another plane crashed into WTC 2. A third plane crashed into the Pentagon. And the last plane crashed into a field in Pennsylvania. According to britannica.com, the attacks were financed by al-Qaeda. The leader of al-Qaeda at the time: Osama Bin Laden believed that the USA were weak and he referred to them as “paper tigers”. britannica.com says that all 19 of the al-Qaeda terrorists died. The attacks on the “Twin Towers” in NYC were extremely deadly and according to history.com about 2763 people killed in New York. The responders to the attacks on the Twin Towers were very effective and I will explain how they were effective. Firstly, the 9/11 responders in New York City saved a lot of lives. According to a book I read called, “10 True Tales: Heroes of 9/11” by Allan Zullo, a lot of people went into the buildings to get people out. Since the buildings were on fire and taking elevators weren’t safe, the firefighters and police officers that went into the WTC’s had to climb all the stairs. Some of the helpers went to the top of the buildings to direct people what to do. Also, helicopters went to the top of the WTC’s to pick people up and bring them to safety. Although not many people could fit in the helicopters, they still saved a lot of lives. Another way that the responders saved lives was after the buildings fell, some respondents went and dug through the rubble and ash to find any survivors. While some responders were helping at the crash site, others were helping people by giving out water to people and sometimes directing people away from the crash site. Due to the fact that many people got injured, nurses and doctors at a variety of different hospitals had to work extra hard.
