The things I learned from 9/11. That fire fighters and police officers lost there lives going into the twin towers and humans were coming out. And nobody would of thought that anyone would attack America cause were so strong. It was only the second attack in U.S soil. Many people lost there lives. At first when the first plane hit people thought it was a accident but twenty minites later another one hit. They said “this is not a accident were being attacked”. That day was horrible.
