All 9/11 Airports Serviced by One Israeli Owned Company
What Really Happened
http://whatreallyhappened.com/WRHARTICLES/ICTS.html

It's one of those times when an innocuous comment in an unrelated news report triggers a revelation.

In the article at http://afrocubaweb.com/news/israelispying.htm there is the following paragraph:

"To make the situation worse, a private security company called ICTS, owned by an Israeli, Ezra Harel, and registered in the Netherlands, was employed at Charles de Gaulle airport to screen passengers boarding US planes. Most of its personnel are ex-Shin Bet officers. The company covers security at Boston's Logan airport, where the American Airlines plane came down after flight attendants and passengers overpowered Reid."

The point of the article was that ICTS knew shoe bomber Richard Reid was dangerous, but allowed him on board a flight from Tel Aviv to Paris. Maybe they did and maybe they didn't. But the idea that an Israeli owned company had inside access to the airport used to launch an abortive terror attack brought to mind the strange message Odigo Systems, another Israeli owned company with offices near the World Trade Towers, received that warned of the impending attacks before the hijacked planes had even left the ground.

Then there was the story of crotch-bomber Umar Farouk Abdulmutallab, who was allowed to board Northwest flight 253 from Amsterdam on Christmas Day 2009. And again, gate security that allowed him to pass was ICTS!
