Judy Wood and Morgan Reynolds are constructing a site about the anomalies of the intact WTC "bathtub" or slurry walls. They suggest that some unknown weapon was used to pulverize the 2 towers so that their full weight did not fall on the slurry walls and damge them. The pulverization of the towers and the strange heat damage to cars are very mysterious, and I think nuclear devices (even pure fusion ones) can be ruled out because of the lack of affects of intense neutron radiation, and the modest 2.1 seismic shock.
