"a claim that high rise buildings routinely have high explosives built in during construction so as to facilitate demolition at the end of their life."

Well, let me see - average projected life of a high rise before demolition - 30-40 years - nope - the upfront cost of doing that would get knocked on the head - and good high explosives are really stable for that length of time, aren't they? :-)

Oh, and plastic explosives generally do not explode when massive heat is applied (they need a compressive shock to detonate them, hence detonators and primers...), but they DO melt and burn easily at the temps FAR below that actually occurred - thus no explosion is possible. The steel fatigued, and just fell apart. When enough of that occurrs - "fa' down"...

"Old style" skyscrapers had a massive weight bearing structure - damage part of it and the rest of it nearby just takes the forces spread over a larger area - remember the WWII plane that flew into the Empire State Building?

The Twin Towers had a "monocoque" style structure - if ONE link fails, then the whole damn structure just chain reacts to self destruction as each neighbouring link succesively overloads - which may HAVE been ok if the steel had not lost its critical temper due to heat. It was designed with asbestos sprayon to insulate it from heat from a potential fire, but it was documented years before that large chunks of that had fallen off.

What with up to 10 floors in each tower damaged (even only partially and on fire) - it was inevetible. I predicted while watching live that the towers would fall in the order they did - it only takes a little physics and engineering to understand why that was also inevetible.


"Look at the footage of the falling towers, on YOUR DVDs, the ones you believe show the truth. Watch a bit of debris falling from the top, and how it overtakes the bulk of the falling materiel, contained by the tower."

A bowling ball only falls faster than a feather because it has less air resistance. You can only make anything fall faster than that speed by having an external source of energy like a 'rocket motor' push it down faster...
