Here's a quote from Slate Magazine (http://www.slate.com/id/2147499/):

Syria had hundreds of files on al-Qaida, including dossiers on those
who had participated-or wanted to participate-in the 9/11 attacks.
Syrian spies had penetrated al-Qaida cells throughout the Middle East,
and Syrian President Bashar Assad was passing on loads of data to the
CIA and the FBI. Some of these tips apparently foiled al-Qaida plots,
including a plan to fly an explosives-laden glider into the U.S. Navy's
5th Fleet headquarters.


Anyone know anything about this?
