Torch then Thermite

I took a pic of the beam with explanation on how beams are pre-weakened with a torch and then thermite charges are used on the remaining sides to make a complete cut around the beam. These pre-cuts can be made without the building being in danger of falling. still plenty of matter to support the building.

Torch then Thermite

A while back I was studying the 45% cut on that one beam that was still standing up and I could see the mass of once moten metal on the 45% cut, but only on the uppermost top portion and the lowermost bottom portion of the cut. In other words, there is 4 sideds to the beam and top and bottom sides were the only side which appeared to have been cut using thermite. The sides where the cut comes down at a 45% appear to have been cut with a blowtorch. I kept saying to myself that these cuts must have been done first and then the thermite charges where set at the top and bottom sides to complete the cutting of the beam completely.

If you look very closly at that beam you can see the grooves alone the two side cuts and which grooves are at an angle alone the cut. this is typically what a cut looks like when using a blowtorch. I was thinking> "Hey... they could have went through and cut all the beams like this so all they would have to do is set charges on two out of four side of the beam. Making these blowtorch cuts could be done in advance whithout the build comming down."

Then I watch the video on this site called "Controlled Demolition Expert Says WTC7 is C.D." and the guy says the same thing...
