September 11, 2001 will be a day that will live in infamy. On that Tuesday morning, terrorists hijacked two Boeing 767s, one operating as American Airlines Flight 11 and the other operating as United Airlines Flight 175 struck the North and South towers of the world trade center respectively. That same day, a Boeing 757 operating as American Airlines Flight 77 crashed into the Pentagon after being hijacked by terrorists and another Boeing 757 operating as United Airlines Flight 93 was hijacked so it could be crashed into the Capitol Building but ended up crashing into a field in Somerset County, Pennsylvania due to the passengers and crew fighting the hijackers.
