Siesmic Evidence Proves Inside Job?

Well Truetweaker1234, how much fun was this? First you get slaughtered in every post you make, then your source! Ouch, that's gonna leave a mark!
 
Oh yea, I forgot one thing about previous post concerning the airplanes striking the support beams; sound travels faster in a denser medium. that would mean that the vibrations of the airplanes hitting the support beams would hit the lower floors before the sound of the impact (traveling in less denser air) would reach the lower floor. I don't know how much faster it would be though. I only know that sound travles roughly 600 mph at sea level. I don't know what the speed is for steel.

The exact speed of sound in steel is 5,960 meters per second (13,332 mph)!

Thus in steel the speed of sound is approximately 5100 m·s-1.

Excellent!
So sounds of the impact would definitely be heard in the basement area coming through the steel supports a short time before the sound of the impact would reach from the air above.

I'm a little too lazy to try to work out the math. Anybody care to figure out what the time difference would be?

Ht of tower 1368 ft iirc
Each floor ~= 12.44 ft
Impact pt 1 94th floor
=> 1169 ft
Impact pt 2 84th floor
=> 1045 ft

1169 ft = 356 m => .06 seconds
1045 ft = 319 m => .06 seconds

vs

600 mph = 268 m/s
356 => 1.3 seconds
319 => 1.2 seconds

Time differential of 1.24 and 1.14 seconds respectively.
 
Oh, I know.. but can't a fellow have a few delusions?

OK, so I have more than most...

BTW: The faeries assure me that the horrors of 9/11 were unexpected, even by the terrorists, and that no explosives, such as are used in demolitions, were present. Then again, they assure me that the troll under the Brookly Bridge hasn't eaten anyone in years, so... :D
 
guys, the propogation times of sound through different media is interesting, but not relevant. The point of this thread is that the data show a seismic spike that occurs 17 seconds before the aircraft hit. Even if you allow for the maximum possilbe error in radar time, 12 seconds, you still have the spike occurring 5 seconds before impact.

Your attempts to fudge the numbers are just that, fudging. You are ignoring evidence that contradicts your hypothesis, a violation of scientific method. The voluminous eyewitness testimony states that an explosion went off in the sub-basement. The seismic record agrees with this.

All your fudging disagrees with the eyewitnesses, and disagrees with the seismic and radar data. You are going to elaborate lengths to attempt to cast doubt on something which is quite simple. Explosions went off in the basement, just like all those people said they did.

Pay attention to this closely

You have not shown the clocks were synchronized


You have not shown the clocks reporting the crash and the seismograph clocks were synchronized.


Do you understand that?

"Guy," repeating something that is false one-hundred times does not make it even a little bit more true.

And you, yourself, going on and on about science and the scientific method is humorous in the extreme. Jolly good!

The calculation was to show that the "explosion" heard in the sub basement by witnesses before they heard the plane impact coming from above may have been due to the vibrations traveling faster through the support structure than the air.

Besides you still haven't shown where the siesmic event of the plane impact are. A plane hitting the steel support structures that are imbedded in solid granite will cause an event of some sort. It would be roughly akin to tapping a tuning fork with its base imbedded in wood or plaster.

isnt LDEO 30 miles from manhattan? truthseeker1234 also fails to account for inaccuracies in calculating propagation times, especially in an urban setting
 
TS, it is amusing to eat pop corn and stand on the sides lines and see your theories being torn apart but simply going right back to the beginning of the thread and asking people to keep on addressing what as already been addressed is silly. You may as well ask those that have explained it to you just copy and paste their replies.

Listen pal, you’ve been shown the false thinking behind these theories. What has been said to you makes far more sense than bombs going off 17 and 14 seconds before the planes hit the Towers.

I didn't happen TS, accept it, move on and wait for your demi gods to put forward yet another theory.

BS101's fear must be along the lines of the CT's claim "if one occurance on 9/11 proves to be an inside job, isn't everything an inside job?"

If the WTC didn't pulverize into a mushroom cloud and leave a crater, so therefor wasn't an inside job, then maybe... WTC 7 wasn't 'pulled' ? And passengerjets actually did crash into the Pentagon and at Shankville?

Personally, I doubt very much they actually heard the impact itself through air. I suspect the second noise was the explosion of the Jet Fuel. For that you'd add an extra 1.5-2 seconds.

You have no evidence whatsoever that these spikes originated at the WTC.

Video evidence already clearly proves there was no explosion at the WTC just before UA175 hit WTC2. Therefore the second of these "spikes" did not come from the WTC. Therefore only the spike before AA11's impact is in issue.

The only evidence of explosive before AA11's impact are the testimonies of a few people who were below ground and cannot see the impact. Their testimonies have either been misrepresented or they themselves have repeatedly changed them. They did not report an explosion. They reported noises.

We have demonstrated an explanation that does NOT require explosives, but matches their testimonies.

It is up to you to provide evidence that the siesmic spike before AA11's impact originated at the WTC. Do this, or withdraw your claims.

And are you aware that blasting occured regularly in a quarry near the LD Observatory? Are you aware that blastings are recorded on 9/11?

I assume the clocks used to identify the times for each of these events were all calabrated to the same time source.

I'm still catching up with this thread, but my career involves accurate measurements and metrology. Pretty much every clock in the world is calibrated to UTC, including the clock on your grandmother's end table. Most have a corresponding offset added for time zone and summer time / DST. The accuracy of those calibrations varies tremendously.
