From their own website we can read how L-3 Global Security & Engineering Solutions, a division of L-3 Communications, got the contract to "provide exercise support in design, development, conduct, and evaluation of NLE2010, the nation’s largest annual Tier 1 operations-based exercise."
According to Wayne Madsen "a long-time L-3 Communications consultant for the National Security Agency (NSA) was, according to our source, one of the very few recipients of the live video stream that caught the first plane hitting the North Tower."
L-3 was also one of the corporations "flagged by the SEC" as having been traded suspiciously before 9/11.
Another corporation involved in the exercises, Bridgeborn, describes the exercises in a press release.
Public Intelligence has published a copy of an overview of the exercises which Fema has asked be taken down.
Another corporation involved with NLE 2010 according to the L-3 article, is Booz Allen Hamilton, owned by the Carlyle Group. Joan Dempsey, top assistant to CIA Director George Tenet, said "I like to call Booz Allen the Shadow IC." IC is short for 'Intelligence Community.' Booz Allen Hamilton has notable members including Dov Zakheim, who is a vice president there. Zakheim was the Pentagon controller when the Trillions went missing the day before 9/11, is a PNAC signatory, contributed to the PNAC Rebuilding America's Defenses article and is mentioned by some as a mastermind of 9/11 for his work as a CEO of Systems Planing Corporation which works on fly-by-remote systems for aircraft. It is also mentioned on several websites that Booz Allen was a client of Blessed Relief, the charity said to be a front for Osama Bin Laden.
