Part of the problem is that people (including engineers) often confuse temperature and heat. While they are related, they are not the same. Thermodynamically, the heat contained in a material is related to the temperature through the heat capacity and the density (or mass). Temperature is defined as an intensive property, meaning that it does not vary with the quantity of material, while the heat is an extensive property, which does vary with the amount of material. One way to distinguish the two is to note that if a second log is added to the fireplace, the temperature does not double; it stays roughly the same, but the size of the fire or the length of time the fire burns, or a combination of the two, doubles. Thus, the fact that there were 90,000 L of jet fuel on a few floors of the WTC does not mean that this was an unusually hot fire. The temperature of the fire at the WTC was not unusual, and it was most definitely not capable of melting steel.‖ (Eager & Musso, 2001)
6. Firefighters were not evacuated from Ground Zero before the collapse of the structures because F.D.N.Y. Chief of Department Pete Ganci knew the history of the buildings involved and the extent of their damage, as well as the fact that the fires were in the process of being put out. Therefore, based on that knowledge, he considered total building collapse a literal impossibility, which was acknowledged in the FEMA Report. As evidence of that fact, when a message from OEM (Office of Emergency Management) that the buildings were going to collapse finally reached him shortly before collapse ensued, Chief Ganci considered that statement so outrageous that he reportedly looked at the person who delivered it and said:
―Who the f*** would tell you a thing like that?‖ Further, and of the same significance, at the moment that global collapse ensued, Chief Ganci looked up and stated: ―What the f*** is this?‖ (Verbatim quote from F.D.N.Y. Deputy Assistant Chief Albert Turi, in whose presence the above statement was made)
8. An EMT (Emergency Medical Technician) who was present at Ground Zero has revealed that he was warned on-scene that Building 7 of the World Trade Center was being brought down by controlled demolition and that a 20-second demolition countdown was broadcast over radio preceding its collapse. He also witnessed “multiple underground support columns of the WTC towers that had been severed before those buildings imploded.” He was present at Ground Zero before, during and after the collapse of the structures and states:
―There were explosions. There were flashes. There was molten metal running down the I-beams of the basement levels like lava flows. I‘ve never seen
anything like it. Yes, planes hit the buildings – anybody who says otherwise is a moron. But the explosions – the rapid, symmetrical sequential explosions – they happened.‖ ―We stood outside listening to the explosions. One after the other, every minute or so. At one point, about 10 minutes before the first collapse, a 30-foot or so section of the courtyard exploded straight up into the air. Just before the collapses, a series of deep, below ground explosions, then numerous explosions in the building‘s upper floors. Then we ran. We felt the same deep explosions before the second collapse. This was not just the planes.‖ ―
9. Firefighters witnessing and acknowledging the “serious explosions” is clearly documented in the following video/audio taken long after the planes had impacted and tower collapses (note the level of debris at ground level):
www.youtube.com... FIREFIGHTER GEORGE KOZLOWSKI: ―We made it around the corner and that‘s when the # hit the fan, right then and there. We heard that loud ‗Ba-Boom!‘ I just - it was like an earthquake, or whatever; a giant, giant explosion. Then this big gust came and I just went flying – maybe thirty, forty feet – tumbling. I got up, got on my hands and knees, because all of that white # was all over me. I just kept crawling. My ears were like, deaf, you know? The thundering series of explosions are after the airliner impacts and the demolition charges are clearly audible on the following clip, where the explosions are even time-stamped on-screen. If you watch nothing else, watch and listen closely to this; 8 EXPLOSIONS are distinctly audible immediately prior to first collapse:
WMV video dowenload (2.8 MB) (for text and video, scroll down slightly at):
whatreallyhappened.com... ―A point to note about the above video is the sounds of the explosions consist of low frequencies only. The absence of high frequencies indicates the sounds were not transmitted through the air to the camera's microphone but through the ground - they reached the microphone via the tripod. This in turn indicates that the explosions occurred below ground level (note where the smoke originates in the video).
somewhere about halfway up, my initial reaction was there was a secondary explosion, and the entire floor area, a ring right around the building blew out.‖
FIREFIGHTER ED CACHIA "It actually gave at a lower floor, not the floor where the plane hit, because we originally had thought there was like an internal detonation explosives because it went in succession, boom, boom, boom, boom, and then the tower came down."
Much the same description is given by another eyewitness to building collapse, former NYPD officer and responder Craig Bartmer. He states that he clearly heard bombs tear down Building 7 as he ran away from its collapse: N.Y.P.D. OFFICER CRAIG BARTMER
"The whole time you're hearing ‗Boom, boom, boom, boom, boom.‘ I think I know an explosion when I hear it."
JOHN SCHROEDER, FIREFIGHTER: ―The elevators just blew right out. We couldn‘t believe it. The plane hits 80 floors up but the elevators explode at least five minutes later? It was unreal.‖ ―We were tossed like a rag doll by another explosion in our building. People were making there way down the stairwells burnt like you couldn‘t believe. We were all shocked because it seemed as if there was fire everywhere, on so many floors. It just didn‘t make sense.‖ F.D.N.Y. FIREFIGHTER ANGEL RIVERA: "When we hit the 19th floor, something horrendous happened. It was like a bomb went off. We thought we were dead. The whole building shook." ―It was like a huge, enormous explosion. I still can hear it. Everything shook. Everything went black.‖
17. In another peer-reviewed study, it was determined that seismic activity clearly identified explosions separate from the jetliner impacts: ―On September 11, 2001, the seismic stations grouped around New York City recorded seismic events from the WTC site, two of which occurred immediately prior to the aircraft impacts upon the Twin Towers. Because these seismic events preceded the collisions, it is clear they were not associated with the impacts and must therefore be associated with some other occurrence. None of the authorities charged with the responsibility for the investigation of the events of 9/11 have proposed a source for these seismic events, nor have they given a valid reason for the difference in times between the seismic events and the aircraft impacts. Only by consideration of the evidence of basement explosions before the aircraft impacts, as experienced by William Rodriquez and 36 others, can an explanation be found for the fact that the seismic stations recorded seismic events originating from the WTC sites prior to the aircraft impacts.‖ ―
FIRE CAPTAIN BRENDA BERKMAN: "We had cleared an enormous collapse zone for that, and it still wasn't big enough. When the thing came down, the rubble and the dust came across the West Side Highway, over and past the rubble from the towers that was there." Indira Singh was an on-scene EMT who reported that she was pre-warned about the collapse of Building 7 and that the context was clear that it was being deliberately demolished: "What happened with that particular triage site is that pretty soon after noon, after midday on 9/11, we had to evacuate that because they told us Building 7 was coming down…I do believe that they brought Building 7 down because I heard that they were going to bring it down because it was unstable, because of the collateral damage…By noon or one o'clock they told us we had to move from that triage site up to Pace University, a little further away, because Building 7 was gonna come down or being brought down…There was another panic around four o'clock because they were bringing the building down and people seemed to know this ahead of time, so people were panicking again and running." Question to E.M.T. Singh: ―Did they actually use the words ‗brought down,‘ and who was it that was telling you this?‖ E.M.T. Singh: ―The Fire Department, the Fire Department, and they did use the word(s), ‗we‘re gonna have to bring it down.‘‖ (KPFA Berkeley, 4/27/2005, Guns and Butter with Bonnie Faulkner)
I see no reason to invent a "decoy plane " .
What you have in fact done, by drawing attention to UA 93's course change at 0959, is further substantiate the OS account that the passengers were on the point of broaching the cockpit which is why the hi-jackers put the plane down.

feebs, I hear the man leaving backwards of the camera, say it.
Could it be you listen to the wrong man, the one who's leaving after that, to the right, still in sight?
The one with the walkie-talkie in his hand.
On the morning of 9/11 in his capacity as Deputy Director, Emergency Services Department, New York City Housing Authority, Mr Jennings and Michael Hess, who is a founding Partner and Senior Managing Director of Giuliani Partners LLC, visited the Office of Emergency Management inside Building 7 only to find it had been abandoned
Jennings: "Upon arriving into the OEM EOC, we noticed that everybody was gone, I saw coffee that was on the desk, and half eaten sandwiches,” he said that he made telephone calls, and was told to leave the building right away.
"When we reached the 6th floor there was an explosion, the landing we were standing on gave way and I was left there hanging, we had to climb back up to the 8th floor,” said Jennings.
Mr Jennings broke a window on the 8th floor with a fire extinguisher, and after attracting the attention of a civilian, both he and Michael Hess were subsequently rescued by the NYFD..
“I was trapped in there for several hours .. both buildings came down, all this time I’m hearing all kinds of explosions .. 'the lobby' was in total ruins .. we were stepping over people and you can tell when you’re stepping over people.”
A fireman escorted both men to street level, whence a police officer told Jennings, “you will have to run because we have reports of more explosions.”

WTC 7 was a classical, but demo-camouflaged, 45 floors demolition, a so-called bottom-up demolition.
