The First Attack: 9/11 WTC sub-level explosions

[Mcluhan]

Seems there was a big explosion in the bsmt of WTC1 and apparently also later in WT2 (there is less info on this one) before each airliner crashed.

Here are the eye witness accounts and seismic data.

Explosions below sub basement level-4 WTC1

Seismic data

If you want to read what Jim Hoffman says about it, go here.

Seismic Records of the Twin Towers' Destruction:

My question is, what do you think these explosions were all about? I.e. tied to what reason? For what reason? Diversion? Accidentally 6 seconds off time but placed to help force notion of quick global evacuation?

So an aircraft hits the building at high speed, exploding into a huge fireball that shakes the whole building no doubt sending shockwaves through its entire structure, some windows get blown out on other floors, and you think that means there was a bomb in the basement??

God. You're dumber than I thought.

Dude, let him write. It's better than comedy.

Jim Hoffman is a software engineer specializing in scientific visualization. I'm guessing he's let his imagination run away with itself. The Lamont-Doherty Earth Observatory in New York, 34 miles from Manhattan, has given much more detailed seismic data that debunks this. According to Arthur Lemer-Lam, associate director, "There is no scientific basis for the conclusion that explosions brought down the towers. That representation of our work is categorically incorrect and not in context".

 

[Mcluhan]

Take your best shot.

 

[Asterix]

Take your best shot.

What the hell is that supposed to mean? You prefer to get interpretations of seismic data from a software engineer who evidently makes his living off of creating simulations and whatever money his 9/11 book is bringing in. I prefer to go to professionals who actually record and interpret seismic activity. Unless you think they're in on this as well.

Unless you think they're in on this as well.

Apparently Mcluhan does. Seemingly it’s the ASCE, the government - seemingly the conspiracy continues across administrations that have no love for each other, also federal, state, and city governments with frequently conflicting interests. Likewise anyone with professional qualifications is suspect.

 

[fuji]

Take your best shot.

At what??? Your argument collapsed faster than the WTC, I mean, we're talking about a "controlled demolition" of any credibility you had left.

 

[luckyjackson]

Eye witness accounts also confirm that moments before the first plane struck, an Arabic looking dude standing outside the towers rubbed his hands together and chuckled malevolently before ducking into an alley. If you guys are too silly to put 2+2 together...

Good on ya Mcluhan

God. You're dumber than I thought.

Testimony by this gentleman seems to indicate that a bomb did go off in the basement moments before the first plane hit the tower.

Thank you. I wonder how many other people will take the time to recognize that. After all, its only the constitution at stake.

And Obama's in on it as well?

What's up for your next "midnight moment" the Income Tax is unconsitutional?

Could be lots of things. Who knows; here's one plausible explanation: The first blast is the shock wave from the impact which likely travelled through elevator shafts, blowing out windows, etc., throughout the building. the fireball on impact was enormous.

Later impacts could be the debris falling and hitting the ground above him, which from the height of the impact would have arrived around 10 seconds after the shockwave from the impact, or might have even fallen off later. The second shock could have also been some internal building support giving way suddenly causing load to shift to a different part of the superstructure.

Could have been any number of other things too all relating to the impact of the plane and resulting structural damages.

From what i have read the statements from the article author were not testimony they were his best estimates of what happened.

The speed of collapse is one thing that is explainable, in free fall an object from that hieght would take 8 seconds more or less, the towers were not in free fall, friction and the action of the upper structure crushing the lower structure as it fell would have slowed it down.

The seismic recordings are what the y are and are open to interpretaion. the administrators of one of the sites that recorded the impacts stated that the interpretations the author applied were incorrect. As Fuji states the initial impact would cause a number of imediate secondary effects one of which would be an overpressure from the upper floors running down the building it would have impacted in the basement given the design of the buildings it could have set off the recorders. The design of the buildings and the media the shock wave had to traverse between the impact and the recorders could also make for interpretation problems given the difference in transmittion speeds of earth air water and the building itself.

Overall I think I will stick with teh generally accepted theory. It at least has fewer obvious holes in it.

He says he was on one basement level and the blast came from basement levels below so intense it literally lifted them off the floor. This was the first blast. There was a second shock from above when the plane hit. have another look.

Right. The elevator shaft likely ends in the basement. Likely the shock wave travelled down the elevator shaft. Probably not only the elevator--there were a variety of things running up and down the middle of the building. People on multiple floors reported an explosion from the elevators. The same thing happened in the lobby, where the shock wave blew out all the windows, and so on.

This was the first blast. There was a second shock from above when the plane hit. have another look.

I'm suggesting that the first blast was the plane hitting, and what he says was the plane hitting was actually the debris from the impact hitting the ground above him (it would take about 10 seconds to fall that far), some secondary violent structural failure, or some other sort of secondary event.

Immediately after the impact you can see the whole towers shift violently a few times before (temporarily) restabilizing. That violent process easily could have sounded like an explosion to people at the bottom of the support columns.

These are not the only explanations--all I am pointing out is that there are lots of plausible explanations for what he saw and heard that do not involve any bomb. Leaping to the conclusion that it MUST have been a bomb is far fetched given the number of other possible explanations.

Why reach for the craziest, most far fetched explanation when there are simpler explanations available?

Perhaps Mr Aaronovitch is simply following the directions handed down from the top of The Times attempting to shame sheeple into blindly following the "official" story about what happened.

Here's what Dan Rather had to say about this:
