Still no source for that claim?

There you might find what you were looking for.

Here are listed all the suppliers, grades and
specifications, physical, chemical and structural
characteristics of the steel parts used in the WTC.

This is a draft for public comment. So feel free to inform

Of course it is possible that there is a conspiracy
to hide the existence of the special steel you mention.

That would make for two conspiracies. One to secretly
make the WTC indestructible and another one to bring
it down.
