"I don't think anybody could have predicted..."
Think again. From the NYT:
American aviation officials were warned as early as 1998 that Al Qaeda could "seek to hijack a commercial jet and slam it into a U.S. landmark," according to previously secret portions of a report prepared last year by the Sept. 11 commission. The officials also realized months before the Sept. 11 attacks that two of the three airports used in the hijackings had suffered repeated security lapses.Via The Next Left.
Federal Aviation Administration officials were also warned in 2001 in a report prepared for the agency that airport screeners' ability to detect possible weapons had "declined significantly" in recent years, but little was done to remedy the problem, the Sept. 11 commission found.
The White House and many members of the commission, which has completed its official work, have been battling for more than a year over the release of the commission's report on aviation failures, which was completed in August 2004.
