Stumble This
Saying a skyscraper is an indestructible testament to strength and durability is bogus. You take out one column and it affects the entire structure of the building. it puts weight on columns that are not supposed to share the load of the missing one. And judging from the impact, it took out more then one column.
So really it makes sense when you have a clue about physics, or weight loads, or structure.
That aside, it would take an incredible amount of extremely well places explosives to bring these buildings down at freefall speeds like that, and not from the top down. 130 tons sounds impressive, but that's 130 tons vs god knows how many tons of steel and reinforced concrete. It's like shooting an arrow into a tree.
best analogy ever...
Best analogy ever... if you're an idiot that doesn't know a damn thing about building systems.
Edit: you seriously think that all the tons of concrete and steel in a building are focused at whatever area the plane hit at?
To gorgon- the arrow in a tree was tongue in cheek, but as an architect wouldn't you say that a pancake collapse at freefall speed is a bit improbable? That that the core and surrounding floors would at least fall at different speeds being structured differently? That there would be SOME kind of delay as it fell, given that the floors below are made to hold more weight that the floors near the top? How can a chaotic completely un-controlled demolition fall so uniformly.. and twice that day! Two buildings hit in different places with different planes and yet both freefall straight down at the same speed and within 20 minutes of each other.
“If there’s any good thing about this it’ that the towers tended not to weaken to one side, “said Taylor. “They could have tipped onto the other buildings…”
The collapse of the WTC Towers mirrored the strategy use by demolitions experts. In controlled demolitions, explosives are placed not just on the lowest three floors but on several consecutive floors..the explosions at the higher floors enable the collapse to gain downward momentum as gravity pulls the full weight of unsupported higher floors down into lower floors ion a snowballing effect.
It cascaded down like an implosion” Says Taylor.
