I am sick and tired of the conspiracy nutcases that say the world trade towers fell because explosives were planted in each of the towers.
From wikipedia:
The two towers collapsed in markedly different ways, indicating that there were in fact two modes of failure. The north tower collapsed directly downwards, "pancaking" in on itself, while the south tower fell at an angle during which the top 20 or so stories of the building remained intact for the first few seconds of the collapse.
Subsequent modeling suggests that in the north tower the internal trusses supporting the building's concrete floors failed as a result of heat-induced warping. This placed additional stress on the bunched core columns, which themselves were losing integrity from both impact damage and heat. When the core columns gave out on one of the impact floors, this floor collapsed into the floor below. Once the collapse started, it was unstoppable; the huge mass of the falling structure had sufficient momentum to act as a battering ram, smashing through all the intact floors below. This theory is supported by witnesses from within the tower stating they heard "something like a heavy freight train approaching". There is some visual evidence that it was the core that collapsed first. It can be seen in videos that the large antenna, which was built on top of the core, starts downward a fraction of a second earlier than the rest of the building.
In the south tower, heat warping weakened the single-bolt connections between the floorplates and the initially intact external columns surrounding the impact hole, effectively creating a "hangman's drop" for that portion of the building above the point of failure. Eventually, the gravity load on these bolts increased beyond the breaking point as the joints, floorplates and columns weakened. Again, the momentum of the collapsing structure was sufficient to smash everything below it.

Basically these twats are ignoring the laws of physics. Though i expect nothing less of them, the twats that they are.
My rant is now over and done with. I don't know why this made me angry for. Though i guess it's down to my scientific way of thinking about a problem coming into play. The claims they make just do not swim with me. The jet fuel, burning office materials and the damaged caused by each impact were enough to bring each tower down. No need to plant explosives in the towers to bring them down. And the maintence crews in each trade tower would have noticed people planting explosives in the towers.
Now that really is the end of my rant.
