Nick Berg was in this area for a while as well, freepers have reported.
I snagged this off a website that shall remain nameless:
MANY PATHS SEEM TO INTERSECT IN NORMAN, OKLAHOMA
In early July 2000, Mohammed Atta and Marwan al-Shehhi visited the Airman Flight School in Norman, Oklahoma.
On or about 29 September, 2000, Zacharias MOUSSAOUI contacted Airman Flight School in Norman, Oklahoma using an e-mail account he set up on September 6 with an internet service provider in Malaysia.
On or about 26 February 2001, Zacharias MOUSSAOUI opened a bank account in Norman, Oklahoma where he deposited approximately $32,000 in cash.
Between 26 February 2001 and 29 May 2001, MOUSSAOUI attended the Airman Flight School in Norman, Oklahoma, ending his classes early.
And more recently...26 September 2005: A University of Oklahoma student charged with bringing an explosive device to an airport pleaded guilty to a misdemeanor charge in federal court in Oklahoma City. Charles Alfred Dreyling Jr. of Norman, Oklahoma faces up to a year in prison and a $100,000 fine at a future sentencing hearing. Dreyling, 24, was arrested in August at the Will Rogers World Airport after security personnel noticed a suspicious object in his carryon bag as he was leaving for a family vacation with his parents. He later told FBI agents the device -- a modified carbon dioxide cartridge filled with gunpowder -- was "basically a pipe bomb," according to court papers that he had forgotten was in his bag. (Former Oklahoma City, OK Mayor Kirk Humphreys-- who was also DREYLING'S landlord-- spoke on behalf of DREYLING at his bail hearing).
On a bus trip to the University of Oklahoma, Zacharias MOUSSAOUI was on the same bus as Nicholas BERG, the American man who was beheaded in Iraq in 2004 by Islamic terrorists. At some point on that trip, MOUSSAOUI asked BERG if he could use BERG'S laptop computer. Government sources said BERG gave the MOUSSAOUI his computer password...
September 11 hijacker Ziad Jarrah’s ticket (United Airlines Flight 93) was purchased from a computer terminal at Oklahoma University.
Norman, OK is also cited on a number of occasions in the best-selling book, the most comprehensive investigative work by Jayna Davis titled The Third Terrorist, about the truck bomb blast that killed 171 souls and destroyed the Murrah Federal Building on 19 April 1995 (An absolute MUST read).
