Open a New INDEPENDENT 9/11 Investigation

We need a new independent 9/11 investigation. I've fabricated Structural Steel for nearly 30yrs.. I studied the design of the Towers and can state wit certainty that it was impossible for them to collapse as NIST concluded. They were designed in a tube and for them to collapse as NIST determined they did,the 47 columns in the center of each
tower would have remained in place and all the floors would have collapse around them..Also they came down at or near "Free Fall" rate,which totally defies Physics. With my 30yrs. in the trade,I know of nothing that turns steel to dust. Please Copy & Paste this link to a very short (less than 2 mins.),pay close attention around 50sec into it and you'll see exposed columns start to fall and turn int dust. https://www.youtube.com/watch?v=7W0-W582fNQ
