9/11 Destroyed America. The events on September 11, 2001, changed the world.

9/11 Destroyed America

It was the excuse for the US government to launch military attacks on seven Middle Eastern countries, causing civilian casualties in the millions and sending waves of Muslim refugees into the Western world. The US government wasted trillions of dollars destroying countries and murdering women and children, while public infrastructure in the US deteriorated, Americans’ homes were foreclosed, and American health needs went unattended. 9/11 was also the excuse for the destruction of the protection that the US Constitution provided to ensure the liberty of the American citizen. Today no American has the protection of the civil liberty that the Constitution guarantees. On September 11, 2001, when a neighbor called and told me to turn on the TV, I stopped what I was doing and turned on the TV. Equations for a falling body - Wikipedia. History[edit] The equations ignore air resistance, which has a dramatic effect on objects falling an appreciable distance in air, causing them to quickly approach a terminal velocity.

Equations for a falling body - Wikipedia

The effect of air resistance varies enormously depending on the size and geometry of the falling object — for example, the equations are hopelessly wrong for a feather, which has a low mass but offers a large resistance to the air. Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe. The Destruction of the World Trade Center: Cherchez la Verite: “Hand Waving” the Physics of 9/11. Manuel Garcia, who has his Ph.D. in Aerospace and Mechanical Engineering from Princeton and works as a physicist at Lawrence Livermore National Laboratory has written a recent series of articles for CounterPunch, which is described by the editors as a “widely applauded primer on the laws of physics and the myths of conspiracists (sic)” concerning the collapses of World Trade Center towers 1, 2, and 7.

Cherchez la Verite: “Hand Waving” the Physics of 9/11

Below, I will take issue with Dr. Garcia’s primer. He doesn’t get MY applause. I too hold a Ph.D. (in Physics) from an Ivy League university (Brown) and have worked as a physicist at a national laboratory (33 years at the Naval Research Laboratory in Washington, DC). Physicists with international reputations hate to be caught making mistakes. But there was only one Einstein. Mercifully, we normally publish in refereed journals, where some of our inevitable mistakes are caught by anonymous peer reviewers prior to publication.

Part One of Dr. Deeper into his introductory paragraphs, Dr. Dr. 9/11 Truth: The Mysterious Collapse of WTC Seven. [originally published in September 2009] At 5:21 in the afternoon of 9/11, almost seven hours after the Twin Towers had come down, Building 7 of the World Trade Center also came down.

9/11 Truth: The Mysterious Collapse of WTC Seven

The collapse of this building was from the beginning considered a mystery. [1] The same should have been true, to be sure, of the collapse of the Twin Towers. But they had been hit by planes, which had ignited big fires in them, and many people assumed this combination of causes to be sufficient to explain why they came down. But WTC 7 had not been hit by a plane, so it was apparently the first steel-framed high-rise building in the known universe to have collapsed because of fire alone.

From a purely scientific perspective, of course, there would have been an obvious answer. AE911Truth report: molten metal under Iran high-rise supports controlled demolition hypothesis. By Craig McKee The similarities to what happened at the World Trade Center on 9/11 are undeniable.

At about 11:20 a.m. local time on Jan. 19, 2017, the 15-story Plasco Building in Tehran, Iran (17 stories if you include two floors underground), fell into a pile of rubble after being on fire for about three hours. Twenty-six died, including 16 firefighters, while 500 businesses lost much or all of their property and 3,000 employees were directly affected. (As is pointed out by an alert reader in the comments below, the date, Jan. 19, is the reverse of 911. I think it is very unlikely that this is a coincidence.)

Since concrete expands at 85% the rate of steel, leaving this expansion out of the calculations of the failure of the shear studs is fraudulent. By Chris Sarns Chris Sarns Part 1 of Chris Sarns’ report, regarding the burned-out fire in WTC 7, is available here. Part 2 (below) was originally published on June 10, 2013. NOTE: Quotes from NIST's WTC 7 reports are shown in Bold Light Blue. NIST used numerous unscientific methods and fraudulent inputs to get the key girder to fail in its computer simulation.

Former NIST Employee Speaks Out, Says Building 7 Investigation Bogus, Govt 'Denied Evidence' A former employee of the National Institute of Standards and Technology (NIST) has stepped forward and criticized the government agency for ignoring the scientific errors found in its report on the collapse of World Trade Center Building 7 (WTC 7) during the September 11, 2001, attacks.

Former NIST Employee Speaks Out, Says Building 7 Investigation Bogus, Govt 'Denied Evidence'

Peter Ketcham, who spent almost fifteen years working at NIST, described how the flawed investigation methods were significantly different from the normal standards used by NIST, in a letter to the editor of the respected Europhysics News magazine. Ketcham’s letter was published in the November 2016 issue and comes just months after the magazine’s August 2016 report examining the Building 7 collapse in detail, which has been downloaded over 350,000 times according to the website.

Peter Ketcham was a contributor to numerous scientific papers during his 14 years as a part of the High Performance Systems and Services Division and later the Mathematical and Computational Sciences Division.

Debunking 9/11 Conspiracy Theories and Controlled Demolition - Free Fall. The time required to strip off a floor, according to Frank Greening, is a maximum of about 110 milliseconds = 0.110 seconds.

Debunking 9/11 Conspiracy Theories and Controlled Demolition - Free Fall

It is rather the conservation of momentum that slowed the collapse together with a small additional time for the destruction of each floor. Below are calculations from a physics blogger... When I did the calculations, what I got for a thousand feet was about nine seconds- let's see,d = 1/2at^2sot = (2d/a)^1/2a is 9.8m/s^2 (acceleration of gravity at Earth's surface, according to Wikipedia), [He gives this reference so you can double check him.]d is 417m (height of the World Trade Center towers, same source)so t = (834m/9.8m/s^2)^1/2 = 9.23sOK, so how fast was it going?

Easy enough, v = atv = (9.8m/s^2 x 9.23s) = 90.4m/sSo in the following second, it would have fallen about another hundred meters. DID THE TOWERS COLLAPSE AT FREE FALL? Before we determine if the Towers and Building 7 collapsed at Free Fall.


First it’s important to learn what free fall acceleration is. What is Free Fall Acceleration? “The Acceleration of Gravity. It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s (32.2 f/s/s), downward (on Earth).” ————- Work Done by Gravity Against Inertia and Air.

On occasion, the public has been asked by George W. Bush to refrain from considering certain conspiracy theories. Bush has made such requests when people were looking into crimes in which he might be culpable. For example, when in 1994 Bush's former company Harken Energy was linked to the fraudulent Bank of Credit and Commerce International (BCCI) through several investors, Bush's spokeswoman, Karen Hughes, shut down the inquiry by telling the Associated Press -- "We have no response to silly conspiracy theories.

World Trade Center Building 7 Demolished on 9/11? 9/11 WTC Building 7 + 2nd Plane Impact. (Before It's News) World Trade Center building 7 was not hit by a plane. it collapsed in its own footprint in free fall time. The fires seen here appear to be very minimal, and although we do not have an exact time of the photo, it was at least after one building had collapsed WTC 911 Projectiles flight 175 After an impact of over to 500mph, some projectiles may be expected to exit the WTC.

This one appears to have its own propulsion, it may be an engine, but appears too large. After the first building collapses, building 7 still seems in very good shape, condradictory to stories that it was on fire all day. Evidence of Directed Free-Energy Technology on 9/11. Chechnya High Rise Burns For 29 Hours With No Collapse, WTC 7? By Joe Martino | Activist Post Chechnya high rise burned for 29 hours On April 3rd Chechnya’s tallest building, a luxury hotel, caught fire and burned for 29 hours before finally being put out. The building is completely destroyed; however, it did not collapse. How it Was Done: 9/11 and the Science of Building Demolition.

#howtheydid911 As public awareness grows about the truth about 9/11, it serves to point out that many features of the towers' destruction fit perfectly with standard patterns of demolition. Evidence which at first seems puzzling is in fact consistent with known demolition techniques. WTC 7 differed from Towers One and Two in that WTC7 was a traditional "bottom-up" implosion.
