Using glass is a favorite trick of the terrorist bomber. Glass is a killer in explosions. I won't make this a commercial by giving the company name, but the company with which I am associated has for 30 years manufactured and installed an optically clear 4-mil and 7-mil security window film that allows glass to sustain a 500-lb TNT bomb from a distance of 111 feet. It is the state of the art product in the world. We begin soon two projects in Times Square.

In the Bali bombing, glass was broken 500 yards away. As an example, if a 400-lb car bomb was detonated 150 feet from your window, the kill and maiming zone inside the building could extend up to about 200 feet within the building.

If you work in a building that might be a target or near a building that might be a target, the facility manager of your structure needs to be doing something to protect you. We protected a building a block and a half away from the Murrah building in OKC. Buildings all around ours had broken windows and tremendous interior damage. We didn't have one window give way and allow the blast to penetrate the structure.

You know, I was pondering what, in retrospect, advice might have been offered to WTC employees. Really nothing, except:

1. Don't go to work.
2. If you must, take parachute.
