John
and Jaro and list:
Concrete is one of the materials that has been used to
insulated structural steel and is better for that task in several respects than
the spray-on isulation used in the WTC. Also the geometry is very
different for an airliner impacting against a vertical containment structure vs.
one distributing itself around the inside of one or more floors of a
high-rise. In one case the fire is confined and is impossible to
attack it effectively. In the other case, the fire is probably in the
open and can be attacked with foam or other agents.
Best regards.
