Given that the THREE steel framed buildings "collapsed"
straight down, through the path of most resistance and at the speed
observed on the videos?

80,000 tons of cold steel, intact in that it had NOT suffered the impact of an aircraft, and yet the topmost bit of the building was said to have "collapsed" down onto the as yet undamaged part, resulting in the total destruction of said building.... what is going on here?

If all you have is "thats stupid" then you have no case at all!

What PROF do you have that 19 suicidal Arabs hijacked 4 airliners and crashed 3 of them into buildings?

What?
