Official GPS Data Reveal Superior Aviation GPS Service Provided To WTC & Pentagon During 9/11 Attacks
As the aircraft attacks of September 11, 2001 unfolded at the World Trade Center (WTC) and Pentagon buildings, maximum and near maximum augmented GPS positioning quality for the entire daylight period was provided to the geographic coordinates for the World Trade Center in New York City and the Pentagon in Arlington, VA. Based on output graphs generated by Trimble’s free and highly regarded downloadable GPS planning software , which utilizes GPS “almanac” data transmitted by the GPS constellation on September 11, 2001 and now archived at the website for the United States Coast Guard , conditions such as GPS satellite visibility and geometric “dilution of precision” are both shown to be at maximum or within minutes of maximum during the aircraft impacts at the World Trade Center and Pentagon. Such augmented GPS service is now in routine use by the U.S. commercial aviation industry to allow aircraft flight management computers to utilize precise aircraft positional information, accurate to within just several meters. This GPS service was activated on a conditional basis by the FAA just one year before the September 11, 2001 attacks . This service provided virtual aerial guidance corridors only 243 feet wide and a 95% confidence that an aircraft's true position will fall within any such designed corridor. The augmented GPS service was also utilized to precisely survey the Ground Zero site immediately after September 11, 2001.  Such corridors can be navigated entirely by autopilot and flight management systems scheduled in 1996 and 1998 to be contained by United and American airlines Boeing 757 and 767 aircraft like those used during the terrorist attacks of September 11, 2001.

On March 16, 2011 U.S. District Judge James C. Mahan dismissed a FOIA lawsuit for numerous FBI investigative records pertaining to the terrorist attacks of September 11, 2001. Case No. 2:09-cv-2199-JCM-PAL, Aidan Monaghan v. Department of Justice et al, sought the release of the following F.B.I. records. An appeal to the U.S. 9th Circuit Court of Appeals is likely.
(1) Records describing aircraft wreckage collection for American Airlines flight 77 and United Airlines flight 93 destroyed on September 11, 2001 in Arlington, VA and Shanksville, PA.; (2) Records describing the make and model of Flight Management Computers (FMCs) or Flight Management System (FMS) and Multi-Mode Receivers (MMR) contained by American Airlines flight 11, United Airlines flight 175, American Airlines flight 77 and United Airlines flight 93.; (3) Records containing inventory control serial numbers for Flight Data Recorders and Cockpit Voice Recorders for American Airlines flight 77 and United Airlines flight 93.; (4) Records regarding 'ACARS' (Aircraft Communications Addressing and Reporting System) communications generated by and transmitted to the four aircraft in question on September 11, 2001.; (5) Records regarding any FBI opinions disseminated by USA Today, describing explosive devices as a suspected cause of the destructions of the World Trade Center buildings in New York city, NY on September 11, 2001.; (6) Records regarding the FBI's collection and/or identification of human remains aboard American Airlines flight 77 recovered from the Pentagon building in Arlington, VA and United Airlines flight 93 recovered from Shanksville, PA following the terrorist attacks of September 11, 2001.; (7) An audio copy of the Cockpit Voice Recorder recording obtained from the Cockpit Voice Recorder recovered from the crash scene of United Airlines flight 93 in Shanksville, PA.; (8) Records pertaining to or establishing in-flight phone calls reportedly placed on September 11, 2001, by passengers on-board American Airlines flight 11, United Airlines flight 175, American Airlines flight 77 and United Airlines flight 93, all hijacked during the terrorist attacks of September 11, 2001.
DEPARTMENT OF JUSTICE, et al.,
The development of the capability of an aircraft Flight Management Computer (FMC) to take control of an aircraft away from a pilot and turn over control to its autopilot system, including apparently Boeing 757's, was underway circa September 11, 2001. The development of a collision avoidance, control override capability utilizing a Boeing 757 is documented as early as 1999. Boeing 757s and 767s containing common avionics, were used during the 9/11 attacks.
"Ultimately, if required, the system could initiate an automatically flown evasive maneuver. Validation flights were completed at the NASA Wallops Flight Facility and in-flight demonstrations of the system were completed at Minneapolis-St. Paul International Airport in November 1999 for FAA officials and other Government and industry representatives. The NASA B-757 ARIES and a Honeywell Gulfstream IV (G-IV) were used in the flight test effort."
NYC Department of Buildings: No Copies of City Issued Permits for Construction Within WTC 7 Found For Years 1999, 2000 and 2001
A Freedom of Information reply from the New York City Department of Buildings reports that copies of city permits for routine or major construction work within World Trade Center building 7 during the years 1999, 2000 and 2001 could not be located. Records for the “ALT 2” category were requested.
“DOB divides construction work into two main categories: New Buildings (NB) and Alterations (ALT). Alterations are further divided into three types—ALT1s, ALT2s and ALT3s—depending upon the scope of work. An ALT1 is a major alteration in which the use or occupancy of an existing property changes. An ALT2 is an alteration in which the use or occupancy of a facility does not change, but includes multiple work types, i.e., plumbing and construction. ALT1s and ALT2s must be filed by a registered architect or licensed engineer."
Freedom of Information Act data from the U.S. Geological Survey for seismic data generated by the crash of U.S. Air Flight 427 in southwestern Pennsylvania on September 8, 1994 suggests that even when a Boeing 737, a smaller but comparable aircraft to the Boeing 757, nose dives into the ground at 300 miles per hour , it will not necessarily generate recordable seismic data. Southwestern Pennsylvania is also the same general location of the crash of United Airlines Flight 93, which also reportedly nose dived into the ground at over 500 miles per hour on September 11, 2001. UA 93’s impact apparently did generate weak seismic signals. The reported crash of American Airlines Flight 77 also on September 11, 2001, a Boeing 757, apparently did not generate a discernable seismic signal.

Video footage depicts United Airlines Flight 175 (UA 175) impacting World Trade Center tower 2 (WTC 2) on September 11, 2001 in New York City via a trajectory comprised of two separate banked turns. The second turn was apparently not required to generate impact. The first turn, which maintains a constant angle of bank (AoB), is evident at 1.2 miles before impact. Although human control of UA 175’s observed maneuvers cannot be ruled out, the precise coordination of variables such as the selections of a correct bank angle and turn start time for the first turn apparently pose challenges to the unaided human control hypothesis. The observed turn stability favors the use of autopilot operation, either functioning in a conventional course control mode or in Control Wheel Steering (CWS) mode. The probability that either of these two control systems were used is discussed. Flight deck images of United and American airlines 757s and 767s suggest that such CWS functions may have been disabled circa 2001. Constant radius turns utilizing plotted waypoints during commercial aviation operations are routinely supported by augmented GPS navigation service and related commercial Flight Management Systems (FMS) available circa 2001. As will be demonstrated, the implementation of UA 175’s observed 1.2 mile constant radius arc, seconds earlier or later than observed, would apparently result in UA 175 missing WTC 2. Estimates of the likely effect of crosswinds on the approach to WTC 2 are also provided. It is noted that a projected impact via the first observed banked turn would have occurred under crosswind conditions capable of generating between 122 and 134 approximate total feet of lateral displacement from the calculated final position of the aircraft if not affected by such crosswinds. Aircraft distances and other calculations are based on reported aircraft speed for UA 175 of 799 feet per second at impact and measured times to impact . The observed speeds of both attack aircraft were extreme by comparison to the typical speeds of similarly descending aircraft. While creating significantly less response time for possible human hijacker pilot course corrections during final target approaches that would demand superior control surface operation, a general vector analysis considering the final course and speed for each aircraft suggests that the unusually high speeds observed would generate greater accuracy of the aircraft while enroute to their targets, as a result of smaller course deflection angles and ground track displacements, created by existing and potential crosswinds.
AFIP FOIA Appeal: 9/11 Investigation Still Open; Pentagon & Shanksville Hijacker Records Exempt From Disclosure
The following is a February 4, 2010 Freedom of Information Act (FOIA) appeal reply from the U.S.Armed Forces Institute of Pathology regarding a request for records that confirm the recovery and identification of terrorists accused of hijacking American Airlines flight 77 and United Airlines flight 93 on September 11, 2001. Such records are reportedly exempt from disclosure under exemption (b)(7)(a) which prohibits disclosure of information which would interfere with an on-going law enforcement investigation and exemption (b)7(c), which also provides protection for law enforcement information the disclosure of which could reasonably be expected to result in an unwarranted invasion of personal privacy of individuals in being associated with criminal activities, including investigators.
According to the AFIP, the FBI considers the investigation into the terrorist attacks of September 11, 2001 as still open.

Port Authority Of NY/NJ: No Records Of Contracts For All Major WTC Renovations Recommended By Year 2000 Property Assessment
The following is a November 25, 2009 Port Authority of New York and New Jersey Freedom of Information (FOI) reply to a request for copies of all contracts regarding renovation work within the World Trade Center towers recommended by the December, 2000 Merrit & Harris Inc. World Trade Center (WTC) property assessment entitled "Due Diligence Physical Condition Survey - World Trade Center". Such work included major renovations upon the core support columns contained within WTC towers 1 and 2 to be completed within one year of the December, 2000 report date, that included rust treatment and asbestos abatement. Records requested previously regarding major renovation work performed by known WTC contractors (Turner Construction) until the morning of September 11, 2001, were reportedly destroyed during the terrorist attacks. Turner Construction managed the controlled demolition of the Seattle Kingdome in 2000.
