steel and thermate


World Trade Center debris 9/11/01

Look at this steel box column.

Notice the 45 degree cut with melted steel residue.

Controlled demolition is accomplished by utilizing thermite shaped charges to quickly cut all load bearing members simultaneously, the construction is then able to collapse in a symmetrical manner, at free fall speed, to end up in it's own footprint. (thermite)
