Solving 9-11:  The Deception that Changed the World
Chapter Five

Why Did Crucial Computer Systems Fail?

“The Ptech story is a crucial piece of 9/11 because the software was used to simultaneously coordinate the FAA with NORAD and the Secret Service.”
– Jamey Hecht, “Ptech, 9/11, and USA-Saudi Terror,” FTW Publications

“Ptech was with MITRE Corporation in the basement of the FAA for two years prior to 9/11. Their specific job is to look at interoperability issues the FAA had with NORAD and the Air Force in the case of an emergency. If anyone was in a position to know that the FAA – that there was a window of opportunity or to insert software or to change anything – it would have been Ptech along with MITRE.”
– Indira Singh, “Risk Architect” at 9/11 Citizens’ Commission, September 9, 2004

“THE HEART OF THE MATTER” – On 9-11, Northeast Air Defense Sector (NEADS) radar operators were confused by the false data “injects”, which resulted in flawed and delayed communications between the FAA and the military.
