Is there any possibility that terrorists could have wired the twin towers with thermite cutter charges . . .?

Question

aswell as using the planes? As a structual engineer for 26 years.
I know that the diffuse flames caused by burning jet fuel along with other building materials is not enough to melt structural steel supports. The world trade center fires with the perfect air to fuel ratio would have peaked at 1000dg celsius.

The structual steel supports would need at least 1500dg celsius
to explain the molten metal that much of the steel members were
turned into?

Thermate not thermite charges with their own o2 supply will melt steel girders like butter .
Its the only explanation this is fact look it up.
Somthing else troubling me is the fact that all three buildings fell as the result of planned demolition, ask any demolition expert or engineer. Buildings do not fall that precisley no matter how many planes you fly at them or from what angle? its just not possible physics wont allow it !

So why aren't the CIA investigating who planted the demolition charges?

Answer 1

You should know, AS A STRUCTURAL ENGINEER, that steel has a melting point at about 2750 degrees farenheit.

You should know, AS A STRUCTURAL ENGINEER, that steel loses half of its strength at about 1100 dg farenheit, and at 1800 dg F it loses about 90% of its strength.

Jet fuel does not burn hot enough (800-1500 dg F) to MELT the steel, and the towers did not come down because the jet fuel melted the steel. The jet fuel burned off in a matter of minutes, but it was the ignition source for other combustible material, that heated the steel enough to weaken it and cause the structural failure. Official investigation reports that pockets of the rubble were burning at about 1832 dg Farenheit.

AS A STRUCTURAL ENGINEER, you should also know that a "pancaking" EFFECT is the result of structural failure of the floor support system, and can be caused by many forms of structural catastrophe, including weakened support by fire, physical damage, etc. The CAUSE of those things can be planes slicing through steel, fires, and yes demolition teams destroy support systems to bring down buildings as well.

Just because the effect is the same doesn't mean the cause is the same. Of course, you already knew that because YOU'RE A STRUCTURAL ENGINEER, right?

AS A STRUCTURAL ENGINEER, you should know how the towers were constructed and study the report before you make conclusions agreeing with a conspiracy theory.

Do your homework with facts, not conspirasites. It will serve your career better.

Answer 2

A study by the Chicago Fire Dept. showed jet fuel burns hot enough to disintegrate concrete. The only accelerate to do that. It has also been stated by many other structural engineers how that great of heat didn't necessarily melt the steel, just weakened it enough to cause failure. Also those jets hitting the buildings at 500+ mph probably didn't help the buildings structural integrity.

However I have heard of the demolition and thermite theory. What hasn't been explained is how anyone was able to sneak in that much explosives without anyone noticing. I think someone in the buildings would ask why they were stripping away to the supports and placing those charges on them.

Answer 3

It is true that thermite would do the job. The discrepancy comes in with the fact that once thermite is actuated with it's catalyst, it burns rapidly, and does'nt stop until there's no more fuel. Were thermite used to help collapse the towers, they would've imploded almost immediately. 2 other possiblle theories are the cumulative thermal buildup from heat's tendancy to rise. Any heat insulator in the building would cause a heat buildup diredctly under the insulator. OR, if there were materials such as magnesium in the building (under most circumstances, a totally safe metal) the heat from burning jet fuel, or thermal buildup could cause the metal to ignite. Magnesium burns at an incredibly high temperature, and this would explain the delay between plane impact and the building's collapse.

Answer 4

In the weeks leading up to 9/11, the security system was shut down several times under the guise of security upgrades and IT wiring upgrades. This is a documented fact. Every floor of each of the WTC towers was shut down a total of 2-3 days over the course of several weeks leading up to 9/11. There was also a major change in security personnel the day before, with the former FBI anti-terrorism czar taking his post as the head of security at the WTC. A team of bomb-sniffing dogs, long a standard part of the WTC security detail, were pulled off the job completely with no explanation 3 days prior to 9/11.

Answer 5

The fact that thousands of American people died is the reason. It remains that there were planes flown directly into the buildings to kill innocent thousands. If there are other means by which that this was accomplished, I'm certain that the government has spent time investigating...but the bottom line is that terrorist planes flew into the WTC building and killed our people. Our government focus is to stop more insane attacks - not necessarily to devote valuable resources to the physics of the attack itself. This is an absurd question. What the f*#k are you questioning anyway? There are plenty of neat and pretty physics experiments you can do/review, without questioning the means of slaughter of thousands of Americans.

Answer 6

didn't need to melt the steel structure. They just needed to weaken it sufficiently for the many thousands of tonnes on top to collapse them... The shock of the floors collapsing would then have been enough for the pack of cards type effect.
The amazing thing is the shock continued vertically all the way down to ground zero.. That takes one hell of a balanced and well built building and also amazing weight distribution of the stuff above.. That makes it itneresting

Answer 7

Guess who's brother's company was contracted for WTC1&2 security. Was security eased up before 911, yes. Were the security bomb sniffing dogs called off the properties before 911, yup. Was there a time in the week before, that the buildings security was controlled and the cameras and computars were rendered non useable, for several days, yes. Did Bush order airport security to ease up on all incoming people and baggage, you know it, check it out if you can't believe it. Did Laura Bush intentionally kid her High School sweatheart because she became pregnant and her boy friend said via con dios miss Laura?

Answer 8

dude im a firefighter and i know that steel loses it strenght at 750 degrees f. not to mention that the burning jet fuel along with the fuel load of the building generated temps of 3000 + deg. F. there was no way those buildings were going to stay up. i lost 343 brothers that day and it ticks me off all these conspiracy therorist that know nothing

Answer 9

Thank God there are still smart people like u are out there. your theory suggests somehow CIA was involved in planning that attack. they needed an excuse to go to war with Iraq so desperately. I still have problems believing that a man in cave (bin laden i mean) is capable of orchestrating such sophisticated plans.

Answer 10

It is a case of the fox guarding the hen house. Peace.
