Some interesting videos:
This video appeared shortly after 9/11 and disappeared many times as it was moved around the Web. To the best of my knowledge it was finally published on YouTube in 2006. There were many reports/theories about what was contained in the portions of the Pentagon and unfortunately without proof this remains to be speculation. Below the embedded video is a link to FBI photos released in 2012 that appear in this video so you decide.
