NGC conducts a forensic investigation to test the tenets of some of the most common conspiracy theories of 9/11 and the mysteries surrounding the attacks. Using high-tech forensic experiments, CGI re-creations, eyewitness footage and in-depth analysis by experts and "truthers," 9/11: Science and Conspiracy examines the alleged conspiracies and available evidence. Then we take a fascinating fly-on-the-wall position as the theorists observe the scientific results and react to the conclusions.
