Hello Michael,

actually somewhere on the net i have seen the Nostradamus prediction
of this event. my point was that some corporations will use anything
to promote their business, such as that album cover. reminds me of
other things i see.

i think all we would have to do to know, who did what- would be to
send an email to the Israelis and ask them. and since we are so
indecisive maybe we could just let the Israelis also carry out the
disciplinary actions as well.
having a background in high rise construction, i can tell you i was
amazed that the structures held up as long as they did on one hand and
amazed that they collapsed on the other hand. let me explain.
i had no idea what type of construction those building were.
evidently i belive that they were contract primarily still
construction rather than concrete as speculated. primarily the dust
everyone is seeing is most likely from the millions of sheets of
sheetrock which is used as a fireproofing agent. in the '60s
sheetrock still contained asbestos, and I believe up until the early
'70s.
there was a lot of concrete on the external curtainwall, it looked as
though the structure had concrete exterior supports vertically. you
can see these vertical supports still standing as the building is
collapsing. these supports act like ribs to help resist swaying as
well as add support. so strongly support for the building was
actually in the exterior walls. once the plane penetrated exterior
wall the fire and collision weakened the internal structure.
by contrast most construction techniques today involve creating a
solid concrete core where your elevator shafts, restrooms, stairways
and utility shafts are all enclosed a monolithic concrete structure.
then your exterior walls are non load bearing. this method of
construction also has the benefits because it allows for maximum
windows space which leases at a premium. on the opposite end of the
spectrum other examples of external load bearing construction would be
the Sears Tower Chicago. you can recognize this by the supports on the
exterior which interrupt your view from the interior.
the reason the building took an hour to collapse can be directly
attributed to the good old asbestos fireproofing which is one hour
rated at columns and two hour rated at the core. I am surprised that
the fire sprinkler system (which I'm guessing that it had) didn't help
any more than it did. even if the lines had been severed it should
have helped much more than I saw. i can tell you this also, the
toughest job in world right now is being one of those rescue workers.
they are actually reliving this event twice now. I am like many on
this list probably who are still in shock. But I would like to
acknowledge the condolences from all our foreign compatriots who
extended their thoughts and prayers to us here in America.
