I don't see how this could be done without closing the building.
re: “it takes weeks if not months to prepare a building for a controlled demolition”
After all the blather, with the 911 conspiratorialists bearing the burden of proof, still, it’s good to do the heavy lifting, one’s self, of thinking in the first person.
Here’s Dr. Alan Sabrosky, former Director of Studies at the US Army War College:
What is not open to debate … is that WTC-7 — the third tower to collapse that day, and the only one not hit by a plane — absolutely was brought down by a controlled demolition, as anyone not trying to shield the attackers knows from a real-time video of its collapse. That is, WTC-7 went straight down into its own footprint in seconds without any visible catastrophic external trauma, which means only some catastrophic internal trauma could have brought it down. And if it had been wired for a controlled demolition, then so were the other towers (WTC-1 and WTC-2) that collapsed. That gives the plane impacts a gruesome cosmetic role, designed explicitly to conceal the true cause of the collapse of the buildings, while shocking the public into something akin to numbness.

Second only to the actual controlled demolition of WTC-7, and supplementing the thesis that with or without impacting aircraft the buildings were brought down by other means, is extensive audio-visual evidence on 9/11 while the Twin Towers were still standing from what became “Ground Zero.” This evidence includes real-time clips of secondary explosions at ground level in both WTC-1 and WTC-2 (you can hear the detonations and see smoke and debris billowing out), reports on many networks of those explosions and of strange vans inside and around those buildings prior to the secondary explosions, reports from EMTs (Emergency Medical Technicians) of the same thing and of people inside and around the lobbies of those buildings who were not emergency personal and were not fleeing the disaster – all of this on 9/11 and widely reported as it happened that same day.
Secondary explosions at ground level where there should be no secondary explosions. The catastrophic collapse of the 47-story WTC-7 into its own footprint in seconds, without any significant external trauma, where by rights there should have been no collapse. Vans with targeting maps, explosives or traces thereof, cameras pre-positioned to film the World Trade Center, and especially Israelis with those vans where there should have been no Israelis present with any of those things in those places at that time.
Generally speaking, there are three requirements for evaluating the origin and prospects for success of all covert intelligence operations: (a) motivation, (b) expertise, and (c) local support for access to the target and post-attack evasion and escape.
Let us look first at motivation. It is a bitter commentary on how far the US has gone from its strategic requirements and its own principles that so many movements and governments around the world not only dislike and distrust the US, but hate it with a passion and with better cause than I care to think about. I recently came across a remark by a Jesuit priest to the effect that “Every time I hear that Israel is America’s only friend in the Middle East, I remember that before Israel, America had no enemies in the Middle East” – a point well worth remembering.
But the interesting thing about the assorted movements and governments that might have an actual or perceived reason to do harm to the US, is that all but one has had a negative incentive to do that: to punish the US for some actual or assumed failings or misdeeds. The one exception is Israel. It has no negative incentives at all (I exclude some real fringe fanatics), simply because without US aid and diplomatic support, it would find itself in even worse straits than did apartheid-era South Africa, and with better cause. But it is the one state with a positive incentive, if it believed it could get away with it, which is to enrage the American public against Muslims generally and Arabs in particular, and to make the US an active belligerent in the region – spending American lives and treasure in the service of Israel’s interests.
Expertise is different and more diffuse. There are many intelligence and special operations forces in the world with the expertise to wire large urban structures for a controlled demolition. There are many combat engineer units in many countries that could do the same thing. And there are many private firms that specialize in them as well. Yet neither Al-Qaeda as an organization, nor any of its known affiliates – much less the 19 named Arabs supposedly on those four planes – possessed that expertise, or anything even remotely close to it; had they done so, the Green Zone in Baghdad would have been a pile of rubble.
But it is local support that is the crucial determinant. All well-crafted covert operations require some measure of local support, official or unofficial, unless the target area is so irredeemably hostile that none is available. Any domestic or foreign intelligence agency targeting the WTC would absolutely have required it, and Mossad would be better placed than any other to access such support for entry, access, execution and escape.
This is especially true, given the security company overseeing the WTC. CIA and/or Defense Department personnel (which is not the same as the CIA or the Defense Department as organizations) could have had access, but only if that had Israeli endorsement – one does not casually cut open walls, implant explosives, run cables and wire everything together in buildings with state-of-the-art electronic surveillance and 24/7 on-site security. Mossad would have no such need for those niceties, given the ownership of the WTC and the management of the company overseeing its security. Remember that we are not talking about large numbers of people in any case: given time to prepare the three buildings and protection from detection, as few as a dozen could have sufficed, a number small enough to be effectively unnoticed in a large organization.
Because it can't...
The first attack on the Trade Center attempted using explosives in the belief that one tower would collapse on to the other.
It didn’t.
bin Laden had studied architecture and knew it was a steel building.
Heat is the enemy of steel, Not explosives. Heat is what bought down the buildings.
That's exactly right. I wouldn't put anything past anyone in the government but I don't think these self proclaimed experts realize just how much and how heavy the debris was from the twin towers. Anything even remotely close was going to have massive steel columns and heavy concrete impact it. They act like the towers fell but no other buildings would have been affected at all.
The building fell entirely because of the events that day. Nothing more, nothing less. No controlled demolition. The nation was caught flat footed. I have always been more interested in any other attacks that could not get off the ground.
It was done over the summer before. Use to be a long video about it but it has been taken down.
It was done while elevator shafts were having maintenance and the mossad “art students” placed the charges.
surveyors were stationed all around...watching the tilt....
Two giant 110 story buildings came crashing down after being hit by jets and sending flaming fuel and debris everywhere.
The impact would have wrecked the foundations from the shockwaves. Bldg 7 was on fire. The steel does not have to melt but soften to till it does not have the strength anymore as designed to hold up the load.
Nearly 3,000 dead and 11,000 wounded by the jets and the building debris.
