The official story (Lie) has this problem to deal with now, since the "intelligence failure" falls apart from the point of view of the agencies named who claim that there were indications, but now refuse to testify in court about it in lawsuits against the airlines. If you assume the official story (blindly, contrary to the evidence) to be true, then why have not any government agencies been faulted for failure to protect America on 9/11, including NORAD? George Tenant instead won a medal of freedom (and that for covering another "intelligence failure" about WMD in Iraq).

In the lawsuit against the CIA, companies including American Airlines Inc., United Airlines Inc., US Airways Group Inc., Delta Air Lines Inc., Continental Airlines Inc. and The Boeing Co. are seeking to interview the deputy chief of the CIA's bin Laden unit in 2001, and an FBI special agent assigned to the unit at that time. The names of both are secret.
