I find it really fascinating that they&#x27;ve gone to such lengths to literally recreate a large portion of the plane from the wreckage in order to better understand what happened.<p>I can&#x27;t help but think though, why weren&#x27;t similar measures taken with Flight 93 (Pennsylvania, 2001-09-11) or Flight 77 (Pentagon, 2001-09-11)? I don&#x27;t wish to allude to any of the many conspiracy theories, but I do find it interesting to see how a &quot;real&quot; crash investigation is done, as opposed to what we&#x27;ve been told about 9-11.
