Nothing went off. There was no nuc. Period. There was, however, evidence of a nuclear reaction occurring. Deuterium, Tritium, and trace heavier elements which had no earthy business being there. What the towers were essentially vaporized with was something none of us have been privy to. It was a combination of a few things... conventional demo charges, nanothermate, and a mass scale example of the Hutchinson effect. An energy weapon developed from the work of N. Tesla, among others. So why was there evidence of a nuclear reaction?? Think cold fusion was bullshit? Thats just what the lying ass 3 letter agencies wanted us to think. Whatever this energy weapon was, evidence is consistent with it being powered by cold fusion.  AS for the plane... I think this is a CGI stunt. Listen in the original and there is sound of something extremely fast right before the impact. Now we pretty much know it was a drone, probably filled with high explosives. But that is purely semantics. 9/11 was a deep state hoax to fund the new war machine. The beginning of their "new world order".  But, the true power of this energy weapon is frightening. It could be used to cause huge earthquakes and devastating tsunamis. So who has control of it now??
