The documentary I saw on the building led me to believe asbestos WAS used on the support beams and on those latticing between the floors.

I saw another program about how they came down that implied the same. But they also said that it would only have extended the time before they fell. Still enough to have gotten more people out.

Halfway through the construction of the first tower, environmental concerns did indeed force the builder to change the specifications of the sprayed on structural member insullation to something not including asbestos. The second tower was built with no asbestos spray at all, using the replacement. Failure Analysis shows that the CHANGE in insullation coating did have an effect... but had it not been changed it would have only extended the time a couple of hours... and you're right... more people would have been saved...

Okay, I thought the second tower used it but when banned they were at a far lower level.

I guess I really need to watch those documentaries again befor making further comments.

Memory ain't what it used to be! lol
