www.mideastweb.org/iraq.htm for starters, or a google search for "hijackers trained in Iraq" yealds amazing results.
My friend, a third-rate website making an unsupported claim hardly proves that Iraq trained the hijackers to storm airliner cabins. Don't you realize this would be MAJOR news if there were any proof? Even the cheesy website you cited was honest enough to say
However, the US government has yet (September 2002) to release any official document providing evidence that links Saddam to Al-Qaeada or the World Trade Center attack.
