Very interesting. However, I suspect that these passengers knew nothing of the impending attack, or they would have left the country before it occurred.
they flew to Lexington KY to hook up with the Saudi owner of the race horse War Emblem - he knew about 9-11 in advance (Gerald Posner's book), and was later found dead of a "heart attack" at age 43.
Why would the few flights which were allowed to take place first be denied by government officials?
Why would flights with Saudis on board be the few flights that would be allowed?
