7. A CIA report on June 12, 2001, said that KSM “was recruiting people to travel to the United States to meet with colleagues already there so that they might conduct terrorist attacks on Bin Ladin’s behalf. On June 22, the CIA notified all its station chiefs about intelligence suggesting a possible al Quaeda suicide attack on a US target over the next few days” (256).

This is particularly poor evidence. It doesn’t mention hijacking at all, or even planes, and the worries about an attack in June weren’t restricted to the US, as the full text makes clear:

Threat reports surged in June and July, reaching an even higher peak of urgency. The summer threats seemed to be focused on Saudi Arabia, Israel, Bahrain, Kuwait, Yemen, and possibly Rome, but the danger could be anywhere--including a possible attack on the G-8 summit in Genoa. A June 12 CIA report passing along biographical background information on several terrorists mentioned, in commenting on Khalid Sheikh Mohammed, that he was recruiting people to travel to the United States to meet with colleagues already there so that they might conduct terrorist attacks on Bin Ladin's behalf. On June 22, the CIA notified all its station chiefs about intelligence suggesting a possible al Qaeda suicide attack on a U.S. target over the next few days. DCI Tenet asked that all U.S. ambassadors be briefed.

That same day, the State Department notified all embassies of the terroristthreat and updated its worldwide public warning. In June, the State Department initiated the Visa Express program in Saudi Arabia as a security measure, in order to keep long lines of foreigners away from vulnerable embassy spaces. The program permitted visa applications to be made through travel agencies, instead of directly at the embassy or consulate.

The idea that this report, even in conjunction with others, might persuade NORAD that “the threat of terrorists hijacking commercial airliners within the United States -- and using them as guided missiles” was more realistic than they’d previously assumed, is simply bizarre.
