In honour of the 15th Anniversary of 9/11, National Geographic Channel is looking back at the very best reporting we have done since this world-changing tragedy first happened using extended excerpts from past specials that relate directly to events leading up to and following the attacks on New York City and Washington DC.

Unfortunately the movie 9/11: The Longest War is not yet available on Netflix. Follow us on Facebook to see when 9/11: The Longest War becomes available on Netflix!
