The new two-hour special provides a comprehensive look at the past 15 years — from the buildup to the attacks as the devastating events unfolded, to the military response in the years that followed — leading up to the present day. 9/11: The Longest War draws from a wide range of sources, including over 40 original National Geographic interviews with survivors, first responders, experts, journalists, politicians and military leaders; news footage and eyewitness videos culled from a rarely seen 400-hour archive; and chilling audio recordings from on board the doomed planes and inside air traffic control. Hear from those who worked inside the World Trade Center, whose snap decisions resulted in narrow misses of the attack. Footage from the Pentagon crash site taken shortly after impact captures a raw view of the devastating aftermath. Confronted by a city on its knees, New York City’s then Mayor Rudy Giuliani opens up about his own emotions in the midst of crisis, even as word reached him of the deaths of personal friends and the very colleagues he would have turned to for counsel. While some of the nation’s top military leaders also weigh in, both Gen. David Petraeus and Gen. Stanley A. McChrystal reflect on the events that forever changed America. Drawing from National Geographic Channel’s extensive and critically acclaimed library of series and specials, 9/11: The Longest War offers a 360-degree perspective of the deadliest attack on American soil and the ongoing war on terror that followed.
