I know the topic of 911 and the WTC collapse has been discussed over and over again, but I still find dr Judy Wood’s approach quite interesting. There are just too many anomalies that cannot be explained using “conventional” theories.
Note the story of firefighters caught in the stairwell on floors 1 and 2, with 1,25 million tons of building above them. Next thing they knew… they saw the sky, and the tower above them was gone.
