Automated Precision Satellite Guidance Of 9/11 Type Aircraft Largely Possible Just Before Attacks
- United Airlines Boeing Aircraft, Along With UPS And NASA 757s And 767s Utilized During Pre-9/11 GPS Tests
- Raytheon/FAA Controlled GPS Satellite Navigation Array Activated 13 Months Before 9/11 Attacks
- October, 2001 Pilot Override System Envisioned Use Of Satellite Auto-Navigation Concept And Communications Termination
Because information collected after the terrorist attacks of September 11, 2001 has raised questions about the alleged ability and motivation of the people accused of piloting Boeing 757 and 767 planes into the World Trade Center, the Pentagon and a field in Shanksville, Pennsylvania, speculation has since lingered regarding the covert use of technology to precisely self-navigate all 4 airliners into targets that day.
Government and aviation industry publications shed light on the development and implementation of pre-9/11 state-of-the-art systems capable of facilitating precise automated navigation of the Boeing 757 and 767 aircraft used during the 9/11 attacks, to a given destination.
"WAAS (Wide Area Augmentation System) is an extremely accurate navigation system developed for civil aviation. Before WAAS, the U.S. National Airspace System (NAS) did not have the potential to provide horizontal and vertical navigation for approach operations for all users at all locations. With WAAS, this capability is a reality ... WAAS provides service for all classes of aircraft in all phases of flight - including en route navigation"

Just 13 months before the September 11 terrorist attacks, the WAAS GPS satellite array was activated by the FAA and operated by "Raytheon" on a preliminary basis.
AMENDED VERSION: Wide Area Augmentation System Signal Now Available
August 24, 2000
"WASHINGTON, DC - After a successful 21-day stability test of the Wide Area Augmentation System (WAAS) signal in space, the U.S. Department of Transportation's Federal Aviation Administration (FAA) declared that it is now available for some aviation and all non-aviation uses ... The system demonstrated one to two meters horizontal accuracy and two to three meters vertical accuracy throughout the contiguous United States ... Raytheon will operate the system for the FAA on a continuous basis"

Only 3 weeks after the September 11, 2001 terrorist attacks, a patent was applied for regarding a system that would override pilot control from an autopilot equipped aircraft and redirect such an aircraft to a predetermined destination via pre-programmed autopilot settings. This patent cites the Differential Global Position Satellite research and development conducted by Honeywell and NASA during the mid-1990s.
""A method for ... deactivating on-board control of the autopilot system; directing the autopilot system to fly the aircraft to a landing."
