It’s been 13 years since the Collapse of the WTC buildings on the 9/11/2001.
We will not re-produce the thousands of conspiracy theories about the event (a Google search turns up about 16.000.000 results..) but it’s always good to trust Science, Engineering and…common sense.
In the Documentary above, you can watch the very interesting story of Professor Steven E. Jones who has dedicated his life the last years to scientifically explain the collapses using materials analysis and experiments.
In September 2005 , the National Institute of Standards and Technology in US, issued the official Final Report for explaining the collapse of the buildings.
A year after, Steven E. Jones wrote a paper that scientifically challenged the NIST Final Report.
What’s your opinion, after all…?
