“At Offutt Air Force Base in Nebraska, President Bush convened the first meeting of the National Security Council for the terrorist crisis at 3:30 p.m. [on September 11, 2001]. [CIA director George] Tenet reported with near certainty that bin Laden was behind the attacks. Passenger manifests showed three known al Qaeda operatives had been on American Airlines Flight 77, which had plowed into the Pentagon. One of them, Khalid al-Midhar, had come to the CIA’s attention the previous year in Malaysia. A paid spy had placed him at an al Qaeda meeting. They had informed the FBI, who put him on a domestic watch list, but he had slipped into the United States over the summer and avoided detection by the bureau.”
