WTC 7: Silverstein's "Pull It" Explanation Examined On September 9, 2005, Mr. Dara McQuillan, a spokesman for Silverstein Properties, issued the following statement on this issue: Seven World Trade Center collapsed at 5:20 p.m. on September 11, 2001, after burning for seven hours. There were no casualties, thanks to the heroism of the Fire Department and the work of Silverstein Properties employees who evacuated tenants from the building. ... In the afternoon of September 11, Mr. Silverstein spoke to the Fire Department Commander on site at Seven World Trade Center. The Commander told Mr. Silverstein that there were several firefighters in the building working to contain the fires. Mr. Silverstein expressed his view that the most important thing was to protect the safety of those firefighters, including, if necessary, to have them withdraw from the building. Later in the day, the Fire Commander ordered his firefighters out of the building and at 5:20 p.m. the building collapsed. No lives were lost at Seven World Trade Center on September 11, 2001. As noted above, when Mr. Silverstein was recounting these events for a television documentary he stated, “I said, you know, we've had such terrible loss of life. Maybe the smartest thing to do is to pull it.” Mr. McQuillan has stated that by “it,” Mr. Silverstein meant the contingent of firefighters remaining in the building. [US Department of State] There is a problem with the above statement, namely there were no firefighters in WTC 7: "No manual firefighting actions were taken by FDNY." [Fema Report] "There was no firefighting in WTC 7." [Popular Mechanics] "By 11:30 a.m., the fire commander in charge of that area, Assistant Chief Frank Fellini, ordered firefighters away from [WTC 7] for safety reasons." [New York Times] Let's have a look at Silverstein's full statement: "I remember getting a call from the, er, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, 'We've had such terrible loss of life, maybe the smartest thing to do is pull it.' And they made that decision to pull and we watched the building collapse." WMV video download (490kB) In summary, the fire department commander said the fire could not be contained, Silverstein said "the smartest thing to do is pull it", and the fire department made the decision to pull. "Pull" is a term used in building demolition... "We're getting ready to pull Building 6" ... "We had to be very careful how we demolished Building 6..." WMV video download (564kB) ...but the US Department of State contends that Silverstein's "pull it" statement refers to withdrawing firefighters from WTC 7. If this was the case then firefighters should have received a message which said something like "World Trade 7 is unsafe. Abandon the building and withdraw from the area." Okay, let's have a look at the language used by firefighters withdrawing from the area of WTC 7: "It's blowin' boy." ... "Keep your eye on that building, it'll be coming down soon." ... "The building is about to blow up, move it back." ... "Here we are walking back. There's a building, about to blow up..." WMV video download (1 MB) The above indicates the message received by the firefighters was "We are going to demolish 7 World Trade. Clear the area." INDRA SINGH EMT: "...by noon or one o'clock they told us we need to move from that triage site up to Pace University a little further away because Building 7 was going to come down or be brought down." HOST: "Did they actually use the word "brought down" and who was it that was telling you this?" SINGH: "The fire department. And they did use the words 'we're gonna have to bring it down' and for us there observing the nature of the devastation it made total sense to us that this was indeed a possibility..." [Prison Planet] It has also been stated that a 20 second radio countdown preceded the collapse of WTC 7. The statement by Silverstein Properties and the US Department of State also contends there were no deaths in WTC 7 because "pull it" was an evacuation order. This is factually incorrect: Speakers for voice evacuation announcements were located throughout the building and were activated manually at the Fire Control Center (FCC) [WTC 7 Report] It would be impossible to miss an evacuation order. "...I'm on top of building 7 just pulling out rubbish. Pulled out a Port Authority cop at about 11 o'clock in the morning..." WMV video download (597kB) "When 7 World Trade Center came down on Sept. 11, an agent on loan from Washington, special officer Craig Miller, perished..." [PDF download (link expired)] "The Secret Service New York Field Office was located in 7 World Trade Center ... Master Special Officer Craig Miller, died during the rescue efforts." [PDF download] The death of Master Special Officer Craig Miller is another inconsistency in the official explanation of Silverstein's "pull it" comment. Why aren't the numerous inconsistencies questioned by the mainstream media?

Here are the statements of firefighters who were there: http://www.nytimes.com/packages/html/nyregion/20050812_WTC_GRAPHIC/Banaciski_Richard.txt " "They told us to get out of there because they were worried about 7 World Trade Center, which is right behind it, coming down. We were up on the upper floors of the Verizon building looking at it. You could just see the whole bottom corner of the building was gone. We could look right out over to where the Trade Centers were because we were that high up. Looking over the smaller buildings. I just remember it was tremendous, tremendous fires going on. Finally they pulled us out. They said all right, get out of that building because that 7, they were really worried about. They pulled us out of there and then they regrouped everybody on Vesey Street, between the water and West Street. They put everybody back in there. Finally it did come down. From there - this is much later on in the day, because every day we were so worried about that building we didn't really want to get people close. They were trying to limit the amount of people that were in there. Finally it did come down." - Richard Banaciski" http://www.nytimes.com/packages/html/nyregion/20050812_WTC_GRAPHIC/Nigro_Daniel.txt "The most important operational decision to be made that afternoon was the collapse (Of the WTC towers) had damaged 7 World Trade Center, which is about a 50 story building, at Vesey between West Broadway and Washington Street. It had very heavy fire on many floors and I ordered the evacuation of an area sufficient around to protect our members, so we had to give up some rescue operations that were going on at the time and back the people away far enough so that if 7 World Trade did collapse, we [wouldn't] lose any more people. We continued to operate on what we could from that distance and approximately an hour and a half after that order was [given], at 5:30 in the afternoon, World Trade Center collapsed completely" - Daniel Nigro, Chief of Department" http://www.nytimes.com/packages/html/nyregion/20050812_WTC_GRAPHIC/Cruthers.txt "Early on, there was concern that 7 World Trade Center might have been both impacted by the collapsing tower and had several fires in it and there was a concern that it might collapse. So we instructed that a collapse area -- (Q. A collapse zone?) -- Yeah -- be set up and maintained so that when the expected collapse of 7 happened, we wouldn't have people working in it. There was considerable discussion with Con Ed regarding the substation in that building and the feeders and the oil coolants and so on. And their concern was of the type of fire we might have when it collapsed." - Chief Cruthers" http://www.nytimes.com/packages/html/nyregion/20050812_WTC_GRAPHIC/Ryan_William.txt "Then we found out, I guess around 3:00 [o'clock], that they thought 7 was going to collapse. So, of course, [we've] got guys all in this pile over here and the main concern was get everybody out, and I guess it took us over an hour and a half, two hours to get everybody out of there. (Q. Initially when you were there, you had said you heard a few Maydays?) Oh, yes. We had Maydays like crazy.... The heat must have been tremendous. There was so much [expletive] fire there. This whole pile was burning like crazy. Just the heat and the smoke from all the other buildings on fire, you [couldn't] see anything. So it took us a while and we ended up backing everybody out, and [that's] when 7 collapsed.... Basically, we fell back for 7 to collapse, and then we waited a while and it got a lot more organized, I would guess." - Lieutenant William Ryan" *********** http://www.firehouse.com/terrorist/911/magazine/gz/boyle.html "A little north of Vesey I said, we’ll go down, let’s see what’s going on. A couple of the other officers and I were going to see what was going on. We were told to go to Greenwich and Vesey and see what’s going on. So we go there and on the north and east side of 7 it didn’t look like there was any damage at all, but then you looked on the south side of 7 there had to be a hole 20 stories tall in the building, with fire on several floors. Debris was falling down on the building and it didn’t look good. But they had a hoseline operating. Like I said, it was hitting the sidewalk across the street, but eventually they pulled back too. Then we received an order from Fellini, we’re going to make a move on 7. That was the first time really my stomach tightened up because the building didn’t look good. I was figuring probably the standpipe systems were shot. There was no hydrant pressure. I wasn’t really keen on the idea. Then this other officer I’m standing next to said, that building doesn’t look straight. So I’m standing there. I’m looking at the building. It didn’t look right, but, well, we’ll go in, we’ll see. So we gathered up rollups and most of us had masks at that time. We headed toward 7. And just around we were about a hundred yards away and Butch Brandies came running up. He said forget it, nobody’s going into 7, there’s creaking, there are noises coming out of there, so we just stopped. And probably about 10 minutes after that, Visconti, he was on West Street, and I guess he had another report of further damage either in some basements and things like that, so Visconti said nobody goes into 7, so that was the final thing and that was abandoned." Firehouse: When you looked at the south side, how close were you to the base of that side? Boyle: I was standing right next to the building, probably right next to it. Firehouse: When you had fire on the 20 floors, was it in one window or many? Boyle: There was a huge gaping hole and it was scattered throughout there. It was a huge hole. I would say it was probably about a third of it, right in the middle of it. And so after Visconti came down and said nobody goes in 7, we said all right, we’ll head back to the command post. We lost touch with him. I never saw him again that day. ****************** http://www.firehouse.com/terrorist/911/magazine/gz/hayden.html Hayden: Yeah. There was enough there and we were marking off. There were a lot of damaged apparatus there that were covered. We tried to get searches in those areas. By now, this is going on into the afternoon, and we were concerned about additional collapse, not only of the Marriott, because there was a good portion of the Marriott still standing, but also we were pretty sure that 7 World Trade Center would collapse. Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o’clock in the afternoon, but by about 2 o’clock in the afternoon we realized this thing was going to collapse. Firehouse: Was there heavy fire in there right away? Hayden: No, not right away, and that’s probably why it stood for so long because it took a while for that fire to develop. It was a heavy body of fire in there and then we didn’t make any attempt to fight it. That was just one of those wars we were just going to lose. We were concerned about the collapse of a 47-story building there. We were worried about additional collapse there of what was remaining standing of the towers and the Marriott, so we started pulling the people back after a couple of hours of surface removal and searches along the surface of the debris. We started to pull guys back because we were concerned for their safety. Firehouse: Chief Nigro said they made a collapse zone and wanted everybody away from number 7— did you have to get all of those people out? Hayden: Yeah, we had to pull everybody back. It was very difficult. We had to be very forceful in getting the guys out. They didn’t want to come out. There were guys going into areas that I wasn’t even really comfortable with, because of the possibility of secondary collapses. We didn’t know how stable any of this area was. We pulled everybody back probably by 3 or 3:30 in the afternoon. We said, this building is going to come down, get back. It came down about 5 o’clock or so, but we had everybody backed away by then. At that point in time, it seemed like a somewhat smaller event, but under any normal circumstances, that’s a major event, a 47-story building collapsing. It seemed like a firecracker after the other ones came down, but I mean that’s a big building, and when it came down, it was quite an event. But having gone through the other two, it didn’t seem so bad. But that’s what we were concerned about. We had said to the guys, we lost as many as 300 guys. We didn’t want to lose any more people that day. And when those numbers start to set in among everybody… My feeling early on was we weren’t going to find any survivors. You either made it out or you didn’t make it out. It was a cataclysmic event. The idea of somebody living in that thing to me would have been only short of a miracle. This thing became geographically sectored because of the collapse. I was at West and Liberty. I couldn’t go further north on West Street. And I couldn’t go further east on Liberty because of the collapse of the south tower, so physically we were boxed in. ************ http://www.firehouse.com/911/magazine/towers.html "WTC Building 7 appears to have suffered significant damage at some point after the WTC Towers had collapsed, according to firefighters at the scene. Firefighter Butch Brandies tells other firefighters that nobody is to go into Building 7 because of creaking and noises coming out of there. [Firehouse Magazine, 8/02] Battalion Chief John Norman later recalls, "At the edge of the south face you could see that it is very heavily damaged." [Firehouse Magazine, 5/02] Heavy, thick smoke rises near 7 World Trade Center. Smoke is visible from the upper floors of the 47-story building. Firefighters using transits to determine whether there was any movement in the structure were surprised to discover that is was moving. The area was evacuated and the building collapsed later in the afternoon of Sept. 11." ************ Furthermore, according to http://www.debunking911.com/pull.htm "Daniel Nigro said there were RESCUE OPERATIONS that were ongoing. He also says it was HE and not Silverstein who ordered the firemen out. "I ordered the evacuation of an area sufficient around to protect our members, so we had to give up some rescue operations that were going on at the time and back the people away far enough so that if 7 World Trade did collapse, we [wouldn't] lose any more people. - Chief Nigro" *********** So the claim that firefighters weren't in danger if WTC7 collapsed or that they weren't "pulled" out is simply false. Either that or all the above firemen are liars.
Instead of relying on mainstream media and the doubtful testimony of the men who covered up the crime of the century by pulling the building you can go to http://www.WTC7.net and see Tower 7 collapse from 3 different angles. All 3 videos show Tower 7 collapsing in 6.5 seconds. None of the three videos show damage sufficient for a collapse of the steel girders. Soon after 911 a 24 story steel girdered skyscraper in Madrd burned for 36 hours without collapsing.
But not from the South Side where a huge hole in the structure was located. It was obscured by smoke from big fires. The Windsor Tower in Madrid was NOT a 24 story steel skyscraper. The core was reinforced concrete and from the 17th floor on down the frame supporting the floors was primarily reinforced concrete. And all the portions of the tower that did depend solely on a steel frame did in fact collapse. But you will not find the truth if you start your investigation with a foundation of "facts" that aren't facts.
6.5 seconds, with the elevator motor cab starting the collapse. How utterly convenient. BAC, you're returned to your usual slimy bullshit - as though you know anything else. "Get back BeOcho!"
Bozo List: (1) Angle, (2) Kamala AGAviator posted on 2007-02-11 18:29:20 ET Physics, engineering and aviation [our specialty] aside, I wonder how TheStateInc 9-11 believers account for the mathematical statistical improbability..no, impossibility.. of 3 buildings, on fire, all with different damage profiles, all collapsing STRAIGHT DOWN, when they were designed to withstand such damage, and when none ever have before in history. Talk about winning the Progressive Jackpot. We need to take these believers to Vegas and see if some of that good Mojo rubs off on us! AGAviator: Me too, me too!!! Bozo me!! While you're at it, since these events happened so long ago, let's stop discussing history altogether. It's all irrelevant according to you. You've demonstrated your lack of intellect. And that is as politely as I can state it.
Gravity.
Why would the top 20 or 30 floors fall straight down to begin with? If the building collapsed due to weakened steel, do you seriously think all four corners of the top of the building would have fallen at the same exact time, and at the same rate of collapse, considering there were 80 to 90 stories of undamaged steel and concrete that it had to crash through? If the collapse happened as the official story describes, where the steel was weakened by fire, then the top of the building would have tipped, and would have either come to a rest at an angle, or slid off of the undamaged section of the building. Additionally, even if the floors pancaked as described by the official story, the building would not have collapsed at the same rate as if it were falling through thin air, but would have taken at least 96 seconds to collapse, as per Dr. Judy Wood, a professor of Mechanical Engineering at Clemson University. A Refutation of the Official Collapse Theory One must also take into consideration that the building turned to dust as it fell, so the available energy to break floors below was diminshed by the pulverization of the concrete and steel. Thus, the floors should not have pancaked, as there was not enough energy left over.
Thats correct. If you look at the videos and photos, NIST wants us to believe that the building and gravity crushed itself. To this day, NIST does not explain the mechanics of the collapse. So lets take WTC 1. We are supposed to believe that 14 floors crushed the entire tower? If you look at the videos, as the building explodes, there is nothing above it but concrete dust. The debris is being ejected out and away from the tower. The steel and dust is outside the tower itself. What is crushing the tower? Air? The real kicker is, as the debris is falling, the tower explosions/collapse almost keep pace with debris falling through the air. Now, I don't subscribe to the 9 sec collapse trap. It took both towers around 15 seconds total. That still is WAY too fast for a "progressive gravity collapse". I think the average time of collapse per floor was around 1/5-1/6 of a second for the towers and 1/8 of a second for WTC 7.
According to BAC's experts, I guess so. Now, I don't subscribe to the 9 sec collapse trap. It took both towers around 15 seconds total. That still is WAY too fast for a "progressive gravity collapse". The 9 to 11 second figures are what NIST and the 9/11 Commission stated, and correspond to the seismographal evidence, but you're right, an extra six seconds doesn't account for the breaking of 90 or so solid undamaged stories of concrete and steel.
The 9/11 Commission did say the towers collapsed in 10 seconds ... but they got a lot of things wrong. NIST did not say the towers collapsed in 9 to 11 seconds. What they said is this: http://wtc.nist.gov/pubs/factsheets/faqs_8_2006.htm "NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2." And neither does seismographic evidence suggest a collapse of 9 to 11 seconds. As the above source notes: "The seismic spikes for the collapse of the WTC Towers are the result of debris from the collapsing towers impacting the ground. The spikes began approximately 10 seconds after the times for the start of each building’s collapse and continued for approximately 15 seconds. There were no seismic signals that occurred prior to the initiation of the collapse of either tower. The seismic record contains no evidence that would indicate explosions occurring prior to the collapse of the towers." And here are videos that you can time yourself to determine the collapse time was more like 15 seconds. In this one, http://video.google.ca/videoplay?docid=65460757734339444&q=9%2F11+eyewitness the collapse occurs at around 6:40. Here's a source that shows frames at half-second intervals from a real-time CNN broadcast feed aired during the attack (http://www.911research.com/wtc/evidence/videos/docs/tower1_dust_cloud_afterglow.mpg). According to http://911research.wtc7.net/wtc/analysis/collapses/freefall.html "the CNN video suggests that it takes about ten seconds for the bottom of the mushrooming dust cloud to reach the ground, and another seven or so for the top to reach the ground. The following composite timeline combines timing estimates of collapse events from the CNN video and the PAL seismic record. It assumes rubble hitting the ground caused the large ground movement, and thus that the crumbling of the tower prior to that caused only minor ground movement. Given that, the times from these pieces of evidence match up remarkably well.
Let's take a look at the first collapse(thanks to BootHill for the graphic) (start) is first visual indication of collapse, (end) is the end of the collapse. NOTES: 1. The unannotated original of the above chart is available from LCSN labs . Boot Hill posted on 2006-02-27 18:18:20 ET (1 image) Reply
Now, honway, surely you aren't claiming that the video imagery from multiple sources (CNN, NBC and others) that clearly shows the collapse took more than 10 seconds ... on the order of 15 seconds, in fact ... are fakes. Because that seems to be the only alternative, if you want everyone to believe that the collapse time was 10 seconds ... which it seems, you do. And just because you show us a graphic annotated by who knows who that the collapse "began" at a certain tim and ended at another, isn't all that convincing. The NIST effort was much more definitive, drawing from many more sources. AND IS CONSISTENT WITH WHAT THE VIDEO IMAGERY CLEARLY SHOWS. What do the seismologists who produced and analyzed that data you post say? "There is no scientific basis for the conclusion that explosions brought down the towers," Lerner-Lam tells PM. "That representation of our work is categorically incorrect and not in context." And finally, note that ImplosionWorld, experts on demolition, is on the record (http://www.implosionworld.com/Article-WTC%20STUDY%208-06%20w%20clarif%20as%20of%209-8-06%20.pdf) stating that "In all cases where seismographs detected the collapses, waveform readings indicate a single, gradually ascending and descending level of ground vibrations during the event. At no point during 9/11 were sudden or independent vibration "spikes" documented by any seismograph, and we are unaware of any entity possessing such data. This evidence makes a compelling argument against explosive demolition. The laws of physics dictate that any detonation powerful enough to defeat steel columns would have transferred excess energy through those same columns into the ground, and wuold certainly have been detected by at least one of the monitors that were sensitive enough to record the structural collapses. However, a detailed analysis of all available data reveals no presense of any unusual or abnormal vibration events."
http://www.pbs.org/wgbh/nova/wtc/ You frequently quote the NIST. In the link above,click on the link to 9/11 Conspiracy Theories and hear Dr. Shyam Sunder of the NIST explain Tower 1 collapsed in 11 seconds and Tower 2 collapsed in 9 seconds. If you cannot believe the data presented by the NIST team, why do you keep posting it?
You are, of course, referring to this particular audio file: http://www.pbs.org/wgbh/nova/wtc/cons-flash.html at the link you provided. Well, my response is this. Even professionals get sloppy in what they say at times (unfortunately feeding you conspiracy theorists). But facts are facts. The real time videos I've posted clearly show that the collapse of the tower took about 15 seconds. And even conspiracy theorists such as Jim Hoffman acknowledge this. And still photos that show large sections of structure descending well ahead of the collapsing level of the structure make it quite clear that the structure did not completely collapse in 9 or 11 seconds, i.e., free-fall speeds. I'm sorry to see that you will persist in this, honway, because then it makes it more difficult to take anything else you promote seriously. By the way, I hope your readers will take the time to watch the various presentations at this link.
