Can you help me about this movie?

It is about 9-11 i remember seeing it when i was little around 2004-2005 somewhere around that time. I was at my friends house. And this movie showed the real thing as if 9-11 was a movie it showed how they planed it then the bombers getting through security at the airport. And how the other plan crash into the pentagon and the other ones crashing through the towers and everything. I really liked it sssssssooooooooooo much. Can you help me find the title of the movie i search all around ebay,google,youtube, and a few video stores in my area. And i cant find it was it band from the states and i cant see it no more. Please help me i realy like to see it. I had 2 cousins that worked in the world trade center and one of died on that may he rest in piece.
