Yep Jet fuel on the floor and intense heat, the clue is debris being forced out the windows...the fireproofing was probably mangled and therefore not effective. At 1000 degrees Celsius the columms, support structures would be melting causing the floor to collapse. Like I said it would have been the heat that would have been the real problem and not the impact so much IMHO.

As basic as it may be, it shows the forces are extraordinary, unlike the conspiracy evidence which is just plain ordinary it seems! :o The numbers you are using is what i'm referring too.
What you described is also mentioned as being INNACURATE in the initial report.
It has to do with your 10m.
It, wrongly, assumes a free fall at that point. For the acceleration to be 9.81, means the collapse, and everything above it, happened instantly. It simply could not. The only way that is even remotely possible is through a controlled detonation.
So, back to the drawing board.....

PS; Complex solutions, still have to fit with in the basic physics, the laws do not change with complexity or scale.
Unless you try and teach them....and copy the same exact errors made in the actual reports.

Sorry for the loss of your friend Baggers. Even harder when, as Mav said, there was hope and prevention of such events in sight.

I've had a look through that and its not bad. The issue i have is with the 90,000L. Didn't the submitted report say that most of this was dissipated on impact, so all the issues of that used in that report are a non-issue.

TGA approves CSL AZ vaccine today, final batch testing and can be released for use. AZ have declared its safe and effective in response to countries who have suspended its use.

So sorry for the loss of your mate [member=61]Baggers[/member] ... I know that feeling and not a day goes by without me thinking of my best friend. They sure leave their mark.

You know the math can't lie, you could halve all the figures from the actual and the resulting energies are still way beyond anything a building could resist. That is how back of the envelope calculations like this work, you don't end up an order of magnitude out.
For example; Looking 1/2 Mass(5% of WTC 1 or 2), 1/2 Gravity(reduced acceleration), 1/2 fall height
E = 22,500,000 x 4.9 x 5
E = 551,250,000 Newtons
F = E/g
F = 551,250,000 / 9.8
F = 56,250,000kg 
Nothing we build today can withstand even that, it's at least an order of magnitude too high for any building to withstand and transmit that energy down through the structure to the foundations like a shockwave.
For comparative reference, the recent Beirut fertilizer blast was about 1/10th the collapse energy of just one WTC.
Ockham's Razor at work, I think I've read that somewhere before!
