Christophera,

Do they pay you by the word , photo or page when you spam?

as always, the shadow government guard dog(s), aka, murderous fascist traitors, are using their 'flashy things' to distract from any meaningful scientific collusion on the demolitions.

don't worry. be happy.

ps, i think scotts, and guest_david benson are both just more common sense sock puppets.
perhaps astaire, too.

it doesn't 'pay' to poison your own well, conman scents. you could be inadvertently 'stealing' your ACTUAL 'allies' identities(that is, if we ANY shill here BESIDES the conman.)

Has anyone seen this? I found it on 9-11Myths......

Information available on U.S. FAA websites, and confirmed in the NIST NCSTAR 1-5 report, indicate that the Boeing 767 aircraft involved in the 9-11 impacts on the WTC Towers carried a number of oxygen cylinders and oxygen generators. A NASA report by T. L. Reynolds, (No. NASA/CR-2001-210903, issued in May 2001), discusses Onboard Oxygen Gas Generating Systems, or OBOGS, and other sources of breathable oxygen on aircraft:

“Oxygen systems, as they are currently designed for use on commercial transport aircraft, include passenger oxygen for use in the event of a sudden loss of cabin pressure (provided by either compressed oxygen or solid chemical oxygen generators) and gaseous oxygen for use by the flight deck crew. There is also portable gaseous oxygen available for medical use and for protective breathing equipment. The use of oxygen on commercial aircraft, required by FAA regulations, does pose a potential fire safety hazard because of the extremely high gas combustion temperatures that can be produced by combustible materials burning in either pure or oxygen-enriched air environments. This is true of any oxygen system in any environment.”

The standard oxygen cylinder carried on all U.S. commercial aircraft contains 3200 liters of O2 stored at 1850 psi when full. Details of the over-pressure relief of these cylinders are provided in a FAA report by T. R. Marker et al., (No. DOT/FAA/AR-TN98/29):

“Different types of pressure relief devices are used for storing breathable oxygen. There are two types of rupturing relief valves, a frangible disc that will fail under excessive pressure (typically 2500 psi) and a thermal disc that will fail when the temperature exceeds 165°F or 225°F, depending on the type. The rupture disc pressure relief device is the only type used on gaseous oxygen cylinders for crew and passenger breathing systems on commercial transport aircraft….. Ironically, the rupture disc type pressure relief devices pose a more serious concern in a fire environment because, with these relief devices, it is possible for the entire contents of the oxygen cylinder to be discharged at elevated temperatures.”


Marker’s report describes studies showing that rupture disc failure occurs within 15 minutes for cylinders exposed to temperatures as low as 200° C.

The standard chemical oxygen generator used in the OBOGS on commercial aircraft consists of a small metal canister equipped with a spring-loaded striker. When activated, a “candle” of sodium chlorate and additives such as barium peroxide undergoes spontaneous thermal decomposition releasing oxygen gas. The OBOGS units installed on most Boeing aircraft contain about 250 grams of NaClO3 per canister that generate about 50 liters of O2 in 12 minutes – an amount of oxygen considered sufficient to supply two passengers during an emergency descent.

NIST report that the Boeing 767s involved in the 9-11 impacts on the WTC Towers carried about 100 canisters per aircraft; each canister capable of 12-minute oxygen generation for a total of 5000 liters of O2 per aircraft; the canisters were located in compartments above the passenger seats. Researcher D. Blake, in a study of the response of aircraft oxygen generators to elevated temperatures, (See report No. DOT/FAA/AR-TN03/35), found that the lowest temperature for self-activation of a generator canister was 315° C. Other tests conducted by Blake showed that more than 80 % of generator canisters heated to 370° C activated during an hour of heating.

Based on the experimental data presented above it appears quite probable that a significant portion of the oxygen carried by the two aircraft that hit the Twin Towers was released prior to the collapse of these buildings. Experimental data also show that gas cylinders undergo acute release of oxygen at much lower temperatures than the chemical generators onboard the aircraft. Furthermore, the chemical generators release oxygen in 50-liter increments involving many locations in the aircraft cabin, while the bottled gas supply would be released in one 3200-liter pulse at the front-end of the aircraft fuselage where the cylinder is wall-mounted.

In one of the tests described by Marker, 600 liters of oxygen was released into a cargo container where a small fire had been deliberately set. The initial discharge of oxygen caused a very violent combustion reaction that ripped open, and subsequently destroyed, the container. Other data from fire tests in oxygen-enriched environments show that cellulose-based materials such as wood, cardboard and paper, burn almost four times faster in air enriched to 40 vol % O2. This increased combustion rate induces a comparable increase in the heat flux from the burning material and results in flame temperatures as much as 600° C higher than the flame for the same material burning in air – thus flame temperatures up to 1500° C are possible.

Based on the calculated trajectory of UA Flight 175 inside WTC 2, the forward cabin area of the aircraft ploughed into floors 80 to 82 of the northeast corner of the building. Thus the 3200-liter oxygen cylinder carried in the crew compartment of Flight 175 came to rest precisely in the area where the bright yellow glow was to later appear. As many videos show, about 50 minutes after impact, fires were well established in localized areas of the northeast corner of WTC 2 – these fires would have gradually heated the entire forward fuselage to temperatures in excess of 200° C. We therefore suggest that the intense yellow glow seen moments before the collapse of WTC 2 was caused by the discharge of the onboard oxygen cylinder and the subsequent enhancement of the pre-existing fires.

Indeed Manning welcomed and praised the NIST report. But that is not the only problem with Brian's argument.

1) It NOT clear that he was saying there was a cover-up. His point was that the selling of steel was short sited.

quote:
Revelation 13:18 says the following:

"This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is a man's number. His number is 666."

This beast, regarded by some as the Anti-Christ described by John, is thus related to the number 666, one of the greatest mysteries of the Bible.

Curiously enough, if you take the sine of 666º, you get -0.80901699, which is one-half of negative phi, or perhaps what one might call the "anti-phi."

The trigonometric relationship of sin 666º to phi is based on an isosceles triangle with a base of phi and sides of 1. When this triangle is enclosed in a circle with a radius of 1, we see that the lower line, which has an angle of 306º on the first rotation and 666º on the second rotation, has a sine equal to one-half negative phi.

In this we see the unity of phi divided into positive and negative, analogous perhaps to light and darkness or good and evil. Could this "sine" be a "sign" as well?

In addition, 666 degrees is 54 degrees short of the complete second circle and when dividing the 360 degrees of a circle by 54 degrees you get 6.66... The other side of a 54 degree angle in a right angle is 36 degrees and 36 divided by 54 is .666.

Phi appears throughout creation, and in every physical proportion of the human body. In that sense it is the number of mankind, as the mysterious passage of Revelation perhaps reveals.

ST911 Chairman and founder Jim Fetzer rewrites history

Fetzer suspects Bush was behind the attempt on Reagan and that members of the Hinckley family set John Hinckley JR. up to be a ‘Manchurian candidate”. In support of this in book on the Wellstone crash, “American Assassination” he wrote on page 68 (1st edition, chap. 4, “poisonous precedents” section), “John Hinckley SR., a major a major Bush campaign contributor, was arrested in 1980 for possessing a .38 caliber pistol, two .22 caliber handguns and fifty round of ammunition. His son John Hinckley JR…”. Just like most of the assertions in the book NO source is provided

LOL!!!! Ummmmm, excuse me can some one tell Mr. PhD. “scholar for ‘truth’ ” that it was John Jr., the son who shot Reagan, not John Sr. the “Bush campaign contributor” who was arrested at the Nashville airport.

Of course this doesn’t have anything to do with the Wellstone crash or Fetzer’s claims about 9/11 but it just goes to show how Fetzer is totally unreliable and how shoddy his research is, he and Jones make a good combina

Mea Culpa --- In doing the approximate energy calculations yesterday, I was off by a factor of a million. Blush! (I blaim it on a tough week...) Correctly now, the PE of each of WTC 1 & 2 has been estimated to be 10^12 Joules = 1,000 gigaJoules. So the energy required to heat steel to yellow hot is approximately one-thousandth of the PE available, per tonne.

Metamars --- I fear that the most elementary considerations of physics shows that all the available PE became heat. Not all the chemical energy, for example lots of paper did not even turn brown, mush less burn. That, of course, does not explain the yellow hot steel found at the bottom of the excavations. I admit to not having an explanation, not even one involving demolition charges or thermite. As a conjecture, the pounding on the top of the steel, 110 floors plus basement levels worth, is the cause. But I do not know how to estimate just how much of a pounding that is... We know that the majority of the steel beams did not significantly fail in compression, so that gives an upper limit on the pounding possible, but I don't have the data.

You seem to be under the impression that hot metal was recovered from WTC 7. Please post some authoritative reason to believe this was, in fact so. There appears to be some confusion regarding the non-recovery of steel from WTC 7 and there is at least some confusion regarding the non-discovery of hot metal from that site.

reasonwhy --- Thank you again for the informative post regarding explosive spalling. In it we once again see that the aluminum does not explode, it is the high-density concrete. (I will admit that many people seeing that molten aluminum jumping out of the pot might call it an explosion... We just don't seem to have the right word to describe this behavior.) In the context of WTC 2, recall that the floors were poured in place light weight, that is, low-density concrete. In these the ordinary aggregate of sand and gravel is replaced by vermiculite, scoria or pumice. I have earlier posted reasons to believe vermiculite was used. In any case, these have pores where the evolving hydrogen can escape without spalling the concrete.

Whilst web trawling I found plenty of adverts for TufFloor and the like, poured on top of ordinary concrete to protect it from spalling during foundry operations. I think this stuff is mostly a light-weight concrete, maybe with additives...

Finally, WTC 7 was designed differently from any of the other damaged buildings. That, plus damage plus a long fire sufficed to destroy it. Those favoring the D hypotheses have yet to answer how anybody could have known in advance that WTC 7 would be damaged and a fire started. The building just to its west was not, AFAIK, damaged. A building across the street to the west of both towers was hit, but no fire started. I know almost nothing about WTC 6, but hope to learn. However, it was much smaller than WTC 7 and with a considerably different design. Can we now give up blogging about WTC 7 and get on with WTC 1, 2 & 6? Please?

And stop using up bandwidth on insults, sticking to the evidence? Please?

I would rather you do an experiment.Take a crucible of molten aluminum (glowing yellow or orange) and pour it near your feet on a concrete floor. Take pictures so they can put it in text books next to the warning above (What not to do). Come back when you get out of the hospital and tell us concrete doesn’t explode.
