[JURIST] The Federal Aviation Administration [official website] received numerous warnings of al-Qaida's hopes to hijack airplanes in the months prior to September 11, according to a previously unreleased report by the National Commission on Terrorist Attacks Upon the United States [official website]. According to an August report by the commission, the FAA had at least 52 warnings and intelligence on al-Qaida between April and Sept. 11, 2001. An FAA spokeswoman said the agency had received warnings, but none were specific enough to tailor specific security precautions. The spokeswoman also said the FAA had been increasing airport security at the time of the attacks. The commission's report remained classified until the government had an opportunity to review it, and it was released by the National Archives [official website] Thursday. The report is not yet available online. AP has more.
