The client list from the software programmer believed to have crashed his plane into the Echelon* building in Austin Texas reads like a guidebook to defense contractors with connections to 9/11, NSA and Homeland Security.
The FBI had his webpage removed (the screen message previously said that the FBI had it removed) from the internet, but of course the client list from the webpage has been archived. As first discovered by Cryptogon, the client list has corporations on it such as Interstate Electronics Corporation, which needed Mr. Stack's help on developing a GPS-based Fight Management System of all things. IEC is a wholly owned subsidiary of L-3 which is a defence contractor with obvious Homeland Security and NSA connections. There is also this report from Wayne Madsen on Oped News of an L-3 consultant to the NSA who had watched a live feed of the first 9/11 plane impact as it happened. L-3 is included among corporations which were investigated by the SEC for unusual stock put-options in relation to 9/11.**
Cylink Corporation***, another on Mr. Stack's client list had as it's Chief Executive Officer, William P. Crowell who "came to Cylink from the National Security Agency, where he held a series of senior positions, including Deputy Director of Operations and the Deputy Director of the Agency. From 1989 to 1990, Crowell served as a vice president at Atlantic Aerospace Electronics Corporation, now a subsidiary of Titan Systems, leading business development in space technology, signal processing and intelligence systems."
Hughes Aircraft, one of Stack's clients, developed the ground mission control segment of the Global Hawk. Another Stack client, Teledyne, is the prime contractor for the Global Hawk, and L-3 supplied its communications system.****
Other clients on the list such as DMC Stratex Networks, AEI Kongsberg and Sorrento Electronics appear also to be defense contractors and probably a closer examination of these and other corporations on Stack's client list will reveal more interesting details.
*Note: the name echelon itself refers to a "signals intelligence (SIGINT) collection and analysis network" coordinated by the NSA.

**As if that weren't enough, L-3 is among corporations cited by Elliot Spitzer as "having been used by Wall Street brokers in “pump and dump” schemes which cost unwary investors tens of millions of dollars" according to Mad Cow Morning News. Also from Mad Cow we learn that Titan Corporation, a subsidiary of L-3, invested in SkyWay Aircraft, a phony company according to Hospicker, whose DC9 was caught with 5.5 tons of cocaine in the Yucatan in 2006. The article also mentions SkyWay's connections to "military intelligence" and the Bush Family and their supporters. Another article from Mad Cow reveals as well the apparent involvment of other interesting Republican Party leaders. (In a later post it has also been revealed Joseph Stack apparently co-owned his hangar at the Georgetown Municipal Airport with someone with the same name as an L-3 executive working for Homeland Security in Austin)
The L-3 subsidiary which Stack worked for, Interstate Electronics Corporation, is chased by at least one story of corruption as well. An article in Defense Industry Daily explains that IEC supplied defective parts used in CSEL emergency radios to locate downed military pilots. Hopefully they were more careful when they had that service contract for the Trident II Missile.
***From Cryptome, "Cylink Corporation has made encryption security products for networking, for over 16 years. Those products are built by foreign nationals and used by businesses, banks and governments around the world, including in the United States. Cylink has managed to export product without United States restriction, including to embargoed nations."
****Hughes Aircraft is also tied by some to the death of Danny Casolaro. Also of interest, we learn from Kevin Ryan's article on 9/11 that the former President of Hughes Aircraft, James Abrahamson, became director of Stratesec (responsible for WTC security after '93) in December 1997.
