At 8:46 A.M., the plane slammed into the North Tower of the World Trade Center. It was carrying nearly a full load of fuel and hit between the 93rd and 99th floors. The North Tower burned for 102 minutes before collapsing to the ground. All people on the plane were killed, along with approximately 1,600 that were either in the tower at the time or responders who came to fight the fire.
At 9:03 A.M., Flight 175 slammed into the South Tower of the World Trade Center. It was flying at nearly full speed and almost full of fuel. The tower collapsed after 56 minutes. All people on board the aircraft plus another 900 people that were in the towers or responding to the emergency.
When this plane slammed into the World Trade Center, it was certain that something was amiss.
At 9:37 A.M. the plane slammed into the side of the Pentagon at pretty much full speed. The damage to the Pentagon wasn't quite as severe as the damage to the World Trade Center. At the time of the crash, there were 125 people in the building because it was a section that was just remodeled. All of those were killed along with the passengers of the aircraft.
It is believed the passengers struck back at 9:57 with the phrase, "Let's Roll". There was a struggle and the plane crashed near Shanksville, PA six minutes later. It was uncertain what the hijacker's intended target was. Speculation was either the Capitol Building or the White House. If you get a chance, watch the movie called "United 93" and that gives a pretty good description of the events. It is also a pretty jarring one because you can put yourself in that situation.
Allegedly, had the passengers not retaken Flight 93, there was a pair of F-16's on a training mission out of Selfridge that were prepared to crash into the Flight. It was not until 10:20A.M. that any official orders to down hijacked aircraft was given. This picture is my own.
Almost immediately after the attacks, all aircraft in the air were ordered to land at the nearest airport. Any planes that were headed to the United States were told to land outside the US borders (either Canada or Mexico). Planes were kept on the ground for at least a week (if I remember correctly). One thing I do remember is that it was an odd day.
On a side note, I do not subscribe into any of the conspiracy theories surrounding this event. But then again, I don't subscribe to the conspiracy theories surrounding Pearl Harbor, the Moon Landings or the Kennedy Assassination. I think conspiracy theories are a way that people deal with things they can't fathom.
