Explosion Sounds and the World Trade Center - Twin Tower Collapses

Many witnesses to the collapse of the Twin Towers of the World Trade Center in New York City describe at least one "explosion" at the time of the collapses. A few eye-witness accounts specifically describe 3 explosions at the initiation of the collapse, whilst others some describe a "crackling" sound. Many people describe hearing a "pop-pop-pop-pop..." or "bang-bang-bang..." as the towers came down1.

[...]

Some examples of video footage which includes audio can be found and this audio does include evidence of explosions, though it is not generally obvious for a number of reasons. Sounds of intense volume recorded at close distances will tend to overload and be distorted by the time they make it onto tape. If a very loud sound such as an explosion overloads the camera's sound circuitry and is followed very quickly by subsequent loud sounds, the individual sounds will be more difficult to identify because the shape of each sound, the attack and decay, will be masked as the audio circuits are completely saturated with signal.


The footnote (1) links to eyewitness reports.

And then the page offers video and audio with explosions.

Here is one such video (avi format). There are two distinct explosions in that video. Listen to it and tell me what you think, Damocles.

Those explosions are then compared to known demolitions (more sound files).

And then the page takes a different look at the WTC collapse audio:



The page goes into a lot of detail, and gives a lot of examples, and then comes up with this: a square-wave reduction of a tower collapse, giving insight into the pancaking-speed; the floor-by-floor detonation.

We've already established by the collapse speeds that there would've been something like 0.1 seconds per 12.5 floor before it would have to be totally destroyed for the buildings to fall as fast as they did. That audio lets you hear how fast this is, and again it's compared with the audio of floor-by-floor events.

The page, again is here.

Screw stairwell B. We got that story through corporate media.

Listen to this and tell me you don't hear two large, distinctive explosions!

And look at the audio analysis above, and look at the sqaure wave reduction. What do you think caused all those steady audio events in fraction-of-a-second intervals?

Did they specifically say they heard no explosives? Or just didn't mention it at all?


A Port Authority captain yelled at Lim to get moving, but he said, “You go ahead,” and he, too, put an arm around Harris, helping to carry her to the fourth floor.

That was when the wind started, even before the noise. “No one realizes about the wind,” says Komorowski.

The building was pancaking down from the top and, in the process, blasting air down the stairwell. The wind lifted Komorowski off his feet. “I was taking a staircase at a time,” he says, “It was a combination of me running and getting blown down.” Lim says Komorowski flew over him. Eight seconds later—that’s how long it took the building to come down—Komorowski landed three floors lower, in standing position, buried to his knees in pulverized Sheetrock and cement.

Are the people who did hear explosions hearing things, lying? Why would the NYFD lie?

YOU are claiming that what they heard were explosions.

YOU have not provided any proof that the sounds were not the sounds of a 110 story building breaking up.



Why would NYFD personnel describe in detail explosions going off one after another?
Shouldn't they know what it was? Did they say it was gas lines or whatever exploding?
No, they said it sounded just like demo charges going off.

(emphasis added)

It also sounded just like a progressive collapse.




I would prefer to believe professional firefighters than a bunch of hysterical, confused, panicked civilians.

who was in stairwell B?




And actualy you can't always hear them, depends on the building and where their placed.


Not by my experience.


Most building when demoed are empty, not full of furniture, carpets, people, all sound absorbers.

[edit on 14/5/2006 by ANOK]


And how did those sound absorbers work for for the exterior columns?

What is this? Sounds like explosions to me.

And what caused the steady blipping in that square wave reduction? Those blips last about as long as it would've taken each floor to collapse by the collapse times, coincidentally. And also coincidentally, they get louder at the end, just as the collapse was coming down closer to the ground. You seem to be skipping over this stuff.

Are there any audio engineers on here that can take a look at this stuff and confirm it?

That QT format is not working properly for me, no sound. From the looks of it, however, the collapse had already started before the first frame of the video.

What would be normal to see for this type of building? What kind of question is that since that was a unique building built up to that time and maybe ever since? Furthermore, how many have been on fire or came tumbling down? All pure spec and that is why the official story can be whatever regime connected people in the field say it was.

But lets get down to business here really...

If a plane loaded with fuel causes a primarily steel building to start collapsing from the top third because city hall would not allow spec fireproofing of the structural steel in the first place during construction... then how likely is it that said building would fall down so nice and clean?

Most important is this: If all the debunkers here are so confident that the planes brought down the twin towers and number 7 by themselves then why was not the steel thoroughly investigated after the collapse? NO-ONE has had a satisfactory answer for that question... no-one!

If a plane crashes and metal fatigue is believed to be a cause then there is an investigation to find out why. One crash led to an investigation so intense that it was determined that insufficient or weak rivets in the nose cone led to the plane crash (forget the crash right now).

The same thing happened at the Pentagon with the crash video's... not one good answer why the trump card was not thrown by the government to end all the conspiracies and let everyone confidently go back to their meagre lives... why not?

Because they are liars!

but thats just me.


This where you guys always trip yourselves up. If the explosives had to be fairly large to cut through the outer structural steel then how did a plane impacting only 3 floors and fires on not that many more cause the whole building to fail?

BTW Howward what is your presidence for the sounds heard to be like a progressive collapse? When in history has a building like the WTC buildings EVER fallen like they did? How can you claim something when there's no historical comparison?

And again I trust the words of people who were there over your opinion.
Firefighters heard explosives, not my theory, not my opinion, fact.

This is what the Chief of Safety for the New York Fire Dept had to say...

"Shortly after 9 o'clock ... [Albert Turi the Chief of Safety for the New York Fire Department] received word of the possibility of a secondary device, that is another bomb going off. He tried to get his men out as quickly as he could, but he said there was another explosion which took place, and then an hour after the first hit - the first crash that took place - he said there was another explosion that took place in one of the towers here, so obviously according to his theory he thinks that there were actually devices that were planted in the building.

Two WTC impacts. Three explosions reported.

One of the secondary devices he thinks that took place after the initial impact he thinks may have been on the plane that crashed into one of the towers. The second device - he thinks, he speculates - was probably planted in the building. ... But the bottom line is that he, Albert Turi, said that he probably lost a great many men in those secondary explosions, and he said that there were literally hundreds, if not thousands, of people in those towers when the explosions took place."


More reports of explosions...

www.whatreallyhappened.com...

More...

Edmund McNally phoned his wife Liz twice following the aircraft impact. Mr McNally said in his second phone call "Liz, this was a terrorist attack. I can hear explosions below me.''

Kim White, WTC 1 survivor...
We got down as far as the 74th floor [...] Then there was another explosion, so we left again by the stairwell.


From official 9-11 dispatch tapes...

* Official: Battalion 3 to dispatch, we've just had another explosion.
* Official: Battalion 3 to dispatch, we've had additional explosion.
* Dispatcher: Received battalion command. Additional explosion.
* [...]
* Dispatcher: Battalion 5, be advised we're trying to contact Battalion 3 at this moment to report north tower just collapsed.

Neil deGrasse eye witness acount...
"As more and more and more and more and more emergency vehicles descended on the World Trade Center, I hear a second explosion in WTC 2, then a loud, low-frequency rumble that precipitates the unthinkable -- a collapse of all the floors above the point of explosion.


Steve Evans, was in WTC 2 when it was hit...
“I was at the base of the second tower, the second tower that was hit,” Evans said. “There was an explosion—I didn’t think it was an explosion—but the base of the building shook. I felt it shake . . . then when we were outside, the second explosion happened and then there was a series of explosions. . . .


(all emphasis'ss's mine)

Need any more?...

Did I label you? No. 'You guys' means you and Howard and any body else in this thread arguing against CD. Make sense?


MY point is taht this isnt hollywood and yer not going to bring down a building of that size with 10lbs of explosives. you'd also need somethign robust enough to survive the fires on the floors that were impacted and i dont know what it would be.


But who said it was only 10lbs of explosives? I'm personally not making any claims as to how it was done, only how it wasn't done. Physically it is near impossible for a building to fall in it's own footprint without help, but it happened to 3 buildings on the same day, all coincidentally owned by the same guy, larry silverstein. You don't find that suspicious?
Why would the explosives have to survive on the few floors that were on fire?
If a plane taking out 3 floors can bring them down, why wouldn't explosives on say 80 floors do the same? The fires were not as big as 'you guys' claim.
The building were designed to take the impact of a 707, which weighs more than a 757 and is only about a meter shorter in length. 707 has 4 engines, 757 has 2.

707 max take off weight 336,000lbs
757 max take off weight 220,000lbs

So the WTC towers should have handled a 757 with no problem.


"I DESIGNED IT FOR A 707 HIT"

BUILDING COLLAPSE SHOCKS TOWERS ENGINEER, ARCHITECT


Frank A. Demartini, on-site construction manager for the World Trade Center, spoke of the resiliance of the towers in an interview recorded on January 25, 2001. "The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting".


www.freepressinternational.com...


but its a double edged sword. we have NO historical comparison so for anyone to say "oh they shouldnt have fallen the way they did so it MUST be controlled demo" is talking out of their 5th piont of contact.


But we have plenty of historical evidence of how buildings fall period, we also have the physics involved. Can't change the physics whatever you do. If it's physically impossible for the WTC towers to fall from plane impacts and fire then what did bring them down?

i read your external sources with a lot of interest. the most interesting part was where you added the bold, but left out a key word.

received word of the possibility of a secondary device, that is another bomb going off.

oh and i liked this one too

The second device - he thinks, he speculates - was probably planted in the building

all context and we can throw things like that at each other all day.


True but taken in context with all the other evidence that abounds, you know add it all together? What about the other quotes? I like your selective de-bunking. Just like Howward pick on stuff thats pointless and leave the stuff they can't answer alone.

i was at a CT training excersise in june of 04.


Well I only have your word on this but anyway it makes no difference, the physics of the event are wrong for a natural collapse. As I've said many times being a professional doesn't make you immune from denial. Some ppl just don't want to see the truth even though they know it deep down. The implications for some is just too much.
