    A decade after the attacks of 9/11, questions remain about who was involved in the terror plot against America.

    Only one person in the United States -- Zacarias Moussaoui, the so-called 20th hijacker -- has been tried and convicted for the murder of over 3,000 Americans. But, as you will see, there were others -- some still living here -- who helped 19 men fly planes into the World Trade Center in New York, the Pentagon in Washington, D.C., and into a field in Shanksville, Pennsylvania.

    Fox News reveals new details of a support network, here in America for decades.

    In this shocking special, we investigate the associates of the 9/11 terrorists, including American-born cleric Anwar Awlaki, who is now on the CIA's capture or kill list. By digging deep into thousands of government records from the 9/11 Commission, the Congressional Joint Inquiry and the FBI, Fox News fills in some of the blanks about who really helped the hijackers across America.

    And, in a Fox News exclusive, why was Anwar Awlaki invited to the Pentagon for lunch after 9/11 when the FBI knew of his relationship with three of the hijackers aboard American Airlines Flight 77?

    As we show in this program, there are compelling reasons to continue to investigate the largest attack on American soil and the secrets of 9/11.
