Shaped Charges and the World Trade Center Collapses

The job of a shaped charge is to cut steel H-beams. “The way we do this is by cutting the beam at an angle which through a series of beams cut at the same angle will tend to make the building shift over and ‘walk'”

The photograph below demonstrates that the WTC beams were not cut by welders.

Because of fuel and time constraints welders would have used a cutting torch to cut the shortest distance possible – straight across the beams. Also, cutting torches cut by forced oxidation, therefore the large amount of once liquid metal congealed on the beam would not be present.
