One Historical event that I live through was 9/11. On september 11, 2001, 2 airliners flew into the World Trade Center in NewYork City. My mom told me that when she found out it happened, she was watching the news and I was playing with toys in the living room. It was a very scary moment. 9/11 affected the United States and the world in many ways, such as airport security. If 9/11 didn't happen, US airports would probably have much less airport security today. 9/11 also affected me in some ways. If 9/11 didn't happen, My family and I as well as the rest of the United States would not stop and remember all of the people the died in the horrible event.
