Who did 9-11? From a science-based perspective the US did 9-11, the US government did 9-11, the American Government did 9-11, the US government was responsible for 9-11... This website alphabetically  lists  the views of expert individuals  and organizations that conclude that the US did 9-11.

The September 11 (9/11, 9-11) 2001 atrocities, in which a total of 2,995 people are reported to have died, destroyed 3 buildings in the World Trade Center, New York, severely damaged  the Pentagon and involved a further incident in which a plane crashed in Pennsylvania (see “September 11 attacks”, Wikipedia: http://en.wikipedia.org/wiki/September_11_attacks ).

The “official version” of 9-11 is well known -  it allegedly involved 4 passenger planes seized by a total of 19 Muslim hijackers (of whom none came from US Alliance war zones of Somalia, Palestine, Lebanon, Syria, Iraq, Iran, Afghanistan or Pakistan);  the North and South Twin Towers  of the World Trade Center (WTC) (which were each struck by a plane) and a third building (WTC7) (which was not struck by a plane) collapsed gravitationally as a result of structural steel weakness from fires;  part of the  Pentagon was destroyed when a passenger plane hit it precisely at the level of the ground floor; and a fourth passenger plane crashed in Pennsylvania after passengers fought with the hijackers.

The “official story” came from the  pathologically dishonest  Bush Administration (see “Study: Bush, aides made 935 false statements in run-up to war”, CNN, : http://www.cnn.com/2008/POLITICS/01/23/bush.iraq/ ). The “official story” is utterly bizarre and unprecedented;  has been presented by groups of people  with an appalling record of lying by omission and commission, namely successive US Administrations, the governments of the US Alliance in general and the Mainstream Media (MSM);  and has been upheld by a process of  highly flawed “official inquiry” (see “9/11 Commission Report”, Wikipedia: http://en.wikipedia.org/wiki/9/11_Commission_Report ).

Further, unlike the sustained Israeli attack on the defenceless USS Liberty in international waters in 1967 (34 US servicemen killed, 171 wounded; see “USS Liberty incident”, Wikipedia: http://en.wikipedia.org/wiki/USS_Liberty_incident ), in the case of 9-11 there were no survivors to bear witness and no survivors to be potentially tried in a court of law.

Credulity was stretched even further when the US and its UK, Australian and NATO allies used the “official story” of 9-11 to launch bloody wars on Afghanistan and Iraq, and to provide “justification” for immensely destructive US Alliance wars in Somalia, Lebanon and Pakistan. In the Occupied Iraq and Afghan Territories post-invasion violent deaths plus non-violent avoidable deaths from deprivation total 2.5 million and 4.5 million, respectively, and a further 0.8 million people have died opiate drug-related deaths worldwide connected with US Alliance restoration of the Taliban-destroyed Afghan opium industry from 6% of world market share  in 2001 to over 90% by 2007 (see UN Office on Drugs and Crime (UN ODC) World Drug Report 2007”: http://www.unodc.org/unodc/en/data-and-analysis/WDR-2007.html  ; “Afghan Holocaust, Afghan Genocide”: http://sites.google.com/site/afghanholocaustafghangenocide/  ; “Iraqi Holocaust, Iraqi Genocide”: http://sites.google.com/site/iraqiholocaustiraqigenocide/ ; “”Muslim Holocaust, Muslim Genocide”: http://sites.google.com/site/muslimholocaustmuslimgenocide/ ).

Indeed there is a huge disparity between about 3,000 people killed on 9-11 and the war-related deaths in Iraq (4.4 million, 1990-2010), Afghanistan (4.5-5.5 million, 2001-2010) and worldwide from Afghan opiates  (0.8 million) that total roughly 9-11 million – thus read my article first published in MWC News entitled  9-11 Excuse for US Global Genocide. The Real 9-11 atrocity: 9-11 Million Dead in Bush Wars”, Afghan Genocide Essays: http://sites.google.com/site/afghanistangenocideessays/9-11-excuse-for-us-global-genocide .

The bizarre claims of the “official version” of 9-11 gave immediate rise to the 9-11 truth movement and in particular Scholars for 9-11 Truth and Justice (see:  http://stj911.org/ and the Journal for 9-11 Studies: http://www.journalof911studies.com/ ) which is science-based and distinct from Scholars for 9-11 Truth (for details of the difference see:

http://911scholars.org/FetzerRespondsJones.html and http://911scholars.org/ ).

While there are many aspects of the “official story” that strain credulity,  the 2 crucial assertions that depart from reality are (1) 3 buildings collapsing at speeds consistent with nearly zero resistance after relatively limited, low temperature fires  and (2) a jet passenger plane allegedly flown by Cessna trainee pilots and evading numerous physical obstacles landing precisely on a dime at the ground floor of the Pentagon.

Just as US Alliance Governments and the Mainstream Media (MSM) resolutely ignore the horrendous loss of life associated with 2 decades of  Bush Wars (9-11 million), so they resolutely ignore crucial scientific evidence pointing to US involvement in the 9-11 atrocities.

 Two key studies provide crucial evidence for (1) the explosive demolition of the Twin Towers and WTC Building 7 (WTC7) on 9-11 and that (2) the low-flying passenger jet plane did not hit the Pentagon on 9-11 (see “Science proves US did 9-11.   Obama accessory after the fact of 9-11”, Afghan Genocide Essays: http://sites.google.com/site/afghanistangenocideessays/science-proves-us-did-9-11 ).

1. Unexploded nanothermite high explosive in all WTC dust samples studied proves explosive demolition of the WTC on 9-11.

The expert state-of-the-art finding by Professor Niels Harrit (Chemistry Department, 8-Nobel-Laureate University of Copenhagen), and his colleagues, of unexploded nanothermite high explosive in all samples of WTC dust analyzed proves that explosive demolition destroyed the Twin Towers and building WTC7. Only the US Government and/or its surrogates (e.g. the Israelis) were able to effect explosive demolition of these 3 buildings (for details of how this was most likely effected see the commentary to “9/11, Antisemitism and Denial”: http://bellaciao.org/en/spip.php?article19187 ;  Marvin Bush, George W. Bush’s brother, was a principal in the company providing security for the WTC, which underwent a security, telecommunications and computer shutdown weeks before 9-11). The discovery of unexploded nanothermite involved various advanced - but quite standard - chemical physics techniques (SEM, BSE, XEDS) available with a single workstation involving Scanning Electron Microscopy (SEM; to image sample surface using a beam of high energy electrons), BSE (Backscattered Electron imaging based on detection of scattered electrons) and XEDS ( X-ray Energy-Dispersive Spectroscopy for chemical elemental analysis ) coupled with DSC (Differential Scanning Calorimetry, which determines the difference in the amount of heat required to increase the temperature of an experimental sample and reference; a DSC trace shows the relationship of heat flux to temperature, and thereby the endothermic or exothermic [e.g. explosive] behavior of the sample). Very small particle size nanothermite is much more explosive than standard thermite. Professor Harrit has described their finding of unexploded nanothermite high explosive in the WTC dust  as akin to discovering not just the murder weapon but finding a “loaded gun”.

2. Eye-witnesses contradict official version of Pentagon attack – evidence that a low-flying plane over-flew and did not hit the Pentagon (noting that this is controversial).

 A three year independent investigation by into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based Citizen Investigation Team researchers who conducted the investigation: "conclusively (and unfortunately) establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skilfully executed deception." (see “Science proves US did 9-11.   Obama accessory after the fact of 9-11”, Afghan Genocide Essays: http://sites.google.com/site/afghanistangenocideessays/science-proves-us-did-9-11 ).

The "Experts: US did 9-11"  website has been created in response to extraordinary lying by omission and lying buy commission of Mainstream Media (MSM) over 9-11. It simply sets out and documents quotations from an alphabetically listed set of science, engineering, military, intelligence, aviation, analysis  and other  experts who reject he “official version” of the 9-11 atrocity and believe that 9-11  was a false-flag operation carried out by the US to justify horrendous, resource- and hegemony-related wars from Occupied Somalia to US robot-bombed NW Pakistan. A sub-set of the experts asserting that the US was involved also believe that America’s dirty tricks surrogate Apartheid Israel was involved or very likely involved in the 9-11 atrocity.
