Christophera is correct in stating that the Twin Towers were constructed
with a concrete core. Although in my original design the core was to be a
steel framed one that decision was overridden by Minoru Yamasaki the
architect.
That core should have resisted the airplane impacts AND the fires.
I have said nothing for four and a half years but can remain silent no
longer. My belief is that only explosives could have caused WTC 1
& WTC 2 to collapse the way they did on September 11, 2001.
