9/11 Brent Blanchard outlines the requirements for the Controlled Demolition of a Steel Frame Building
Blanchard exploits a common misconception -- that because demolitions are usually engineered to proceed from the ground up, all demolitions would necessarily have to be engineered that way. This is of course false, since explosive charges could be placed anywhere in a building and detonated in any order desired. Obviously, the demolitions of the Twin Towers, being designed to support the official narrative of events, started from around the crash zones.
lol you are quoting an idiot and someone who loves disinfo through BS.
9/11 Seismic Recordings
Brent Blanchard devotes section 4 of his paper to the issue of seismic recordings on 9/11. Blanchard is Senior Editor of ImplosionWorld, a website which posts details of explosive demolitions, and also Director of Field Operations at Protec Documentation Services, Inc. Protec works in the field of vibration monitoring and structure inspection, a key service to both the construction and demolition industries.
Vibration monitoring performed by independent experts has long been considered crucial for companies carrying out explosive demolition, because owners of nearby buildings are keen to sue if any cracks or other structural damage appears.
The field seismographs used by Protec and others provide the key scientific evidence for disturbances that may have caused damage, and there were a number of such seismographs operated by Protec on 9/11 in the vicinity of Ground Zero, for monitoring construction sites. Blanchard tells us that data from these machines, and seismographs operated elsewhere, all confirm single vibration events recording the collapse. None of them record the tell-tale 'spikes' that would indicate explosive detonations prior to collapse. In his words:
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 would 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 presence of any unusual or abnormal vibration events.

2. Mr. Loizeaux's false and self-serving statements are designed to market his company, and one would be wise to question anything he says. He does not have a reputable standing in the industry.
NIST NCSTAR 1-9, Vol 1, (Nov. 2008), p. 298 / PDF p. 342:
"As all of the emergency responder restructuring operations were underway, three people became temporarily trapped inside WTC 7. Two New York City employees had gone to the OEM Center on the 23rd floor and found no one there.(16) As they went to get into an elevator to go downstairs, the lights inside WTC 7 flickered as WTC 2 collapsed. At that point, the elevator they were attempting to catch no longer worked, so they started down the staircase. When they got to the 6th floor, WTC 1 collapsed, the lights went out in the staircase, the sprinklers (at an unspecified location) came on briefly, and the staircase filled with smoke and debris. The two men went back to the 8th floor, broke out two windows, and called for help. Fire fighters on the ground saw them and went up the stairs."

Transformers with automatic circuit breakers and heat-resistant insulating oil should blow why?
Con-Ed staff didn't report any problems. And the substation was shut down around 4:34p.m.
This video was recorded just before noon.
Additionally, according to Con-Ed, the power at whole WTC complex was out before 10:00 a.m.
page 9 of 11 :
NIST's determination of 8:46:30 time of first “impact” is artificial. It is not only erroneous, but may be specious if time manipulation is the motive. This phony time for AA Flt 11 is directly contradicted by the statement made by the NTSB and is not supported by the radar data supplied by the NTSB. The last radar signal from the aircraft before impact was received at 8:46:40, ten seconds after the time that NIST now says is when the aircraft impacted the Tower.
One wonders again if the NIST 2005 contract with Dr. Kim to re-analyze the seismic times is also an attempt at time manipulation in order to find credibility for the bogus 8:46:30 NIST time. An audit by independent seismological experts to determine the authenticity of the revised seismic times would be in order to resolve this matter. --snip--
page 11 of 11 :
This analysis has examined the evidence of basement explosions as given by William Rodriguez and others and has shown by the evidence given by William Walsh, and by examination of the Tower’s elevator layout, that it is not physically possible that these could have the aircraft impact as their source.
The analysis has identified further information from Jenny Carr and shown that this confirms the evidence of William Rodriguez that the basement explosions preceded the first aircraft impact by nine seconds. Examination of the various times given for the seismic events and aircraft impacts, detailed by the FAA, the NTSB and the LDEO original seismic analysis confirm that there was a time delay between the basement explosions and the
aircraft impact.
page 5 of 11 :
TIME DELAY FROM BASEMENT EXPLOSIONS TO AIRCRAFT IMPACT
The authors have located evidence that possibly shows how long the time was between the initial explosion and the later impact of AA Flt 11 at WTC1.
Jenny Carr was at a business meeting with others on the morning of 9/11 at 1 Liberty Plaza, and a recording was being made of that meeting. During this recording a first explosion is heard, and then a second one about 9 seconds later. This data still needs to be corroborated, and both authors and the Scholars for 9/11 Truth are involved in this; however, it is worth presenting at this time. This was found inside a movie compendium.
(LT : Found it back. It was "9/11 Controlled Demolitions of September 11, 2001"). To repeat, this needs further corroboration.
Link: Jenny Carr, Video - 9 Seconds and go in 14 minutes, 30 seconds.
page 6 of 11 :
FAA TIMES
Within the FAA (Federal Aviation Administration) its "Summary of Air Traffic Hijack Events September 11, 2001” are found the impact times of 8:46:35 and 9:03:14.
Link: FAA Summary of Air Traffic Hijack Events September 11,2001
(LT : no link anymore, had to find it myself :
direct link to the FAA report's 59 pages )
What is interesting is, when the 9 seconds found on the Jenny Carr tape are added to the original LDEO seismic time of 8:46:26, the result is 8:46:35, the exact FAA impact time for AA Flightt 11.
0846:31
Primary radar tracking of AAL11 was lost.
0846:31 Primary radar tracking of AAL11 was lost.
0846:35 Impact at World Trade Center.
0903:14 Second Impact at World Trade Center.
page 3 of 11 :
Radar is based upon microwaves that travel at the speed of light, so error variance is not stated. The Commission Report has the impact times. Their data set is based upon actual flight data that ended when the Towers were struck.
There is no question: AA Flight 11 died at 8:46:40 and UA Flight 175 at 9:03:11 [UTC – 4 hrs]. Since the planes crashed at those times, the question is: What caused the LDEO times 14 and 17 seconds earlier? What caused those seismic spikes?
Their time of EDT 17:20:33 must have been based on the deep sound in the video of WTC-7's collapse.

wouldn't read Blanchard's garbage. He has no experience with explosives,blasting or demolition. He is not an engineer either. He maintains an implosion website and during the day he monitors vibrations on pile driving jobs.
He is a self proclaimed "expert"

A Critical Analysis of the Collapse of WTC Towers 1, 2 & 7 From an Explosives and Conventional Demolition Industry Viewpoint
By Brent Blanchard
August 6, 2006
"for explosives to be considered as a primary or supplemental catalyst, one would have to accept that either a) dozens of charges were placed on those exact impact floors in advance and survived the initial violent explosions and 1100+ degree Fahrenheit fires, or B) while the fires were burning, charges were installed undetected throughout the impact floors and wired together, ostensibly by people hiding in the buildings with boxes of explosives. There is no third choice that could adequately explain explosives causing failure at the exact impact points.
"The chemical properties of explosives and their reaction to heat render scenario A scientifically impossible and scenario B remarkably unlikely."

Brent Blanchard obviously knows what he is talking about.
Lol changed his mind much? How much did he get for that?
Or did TPTB threaten him and his family that they will do a Barry Jennings on him?
He is correct the World Trade Center building 7 was NOT destroyed with explosives.
but isn't it obvious that explosions did occur?
