On the morning of September 11, 2001, four airliners, two Boeing 767 and two Boeing 757 was hijacked by nineteen terrorists in order to make them crashing against highly symbolic places of the United States. The four airliners were off 45 between 7 am and 8 am 10, but they were faced with delays ranging from ten to forty-one minutes. So the Flight 11 took off at 7 am 59, Flight 175 to 8 h 14, Flight 77 at 8 am 20 and Flight 93 at 8 pm 4224.
After the takeover by suicide bombers, Flight 11 was kept for thirteen minutes in one direction (north-west), which kept him away from his goal. This choice is found for Flight 175 with his detour over New Jersey to return to Manhattan from the south. This trait is also shared by AA77 and UA93 flights: the lateness of aircraft control (after twenty-six to forty-five minutes) resulted in a significant distance from their target.
