In the wake of the September 11 terrorist attacks on America, the Federal Aviation Administration immediately ordered all flights in the United

States grounded, and that ban stayed in effect until September 13. (Even then, for that first day commercial carriers were mostly either completing the interrupted flights of September 11 or repositioning empty aircraft in anticipation of the resumption of full service. New passenger flights did not generally resume until the 14th.) During that two-day period of full lock-down, only the military and specially FAA-authorized flights that delivered life-saving medical necessities were in the air. The enforcement of the empty skies directive was so stringent that even after the United Network for Organ Sharing sought and gained FAA clearance to use charter aircraft on September 12 to effect time-critical deliveries of organs for transplant, one of its flights carrying a human heart was forced to the ground in Bellingham, Washington, 80 miles short of its Seattle destination, by two Navy F/A-18 fighters. (The organ completed its journey after being transferred to a helicopter.)

The claim that bin Laden family members (and other Saudis) were allowed to secretly fly out of the U.S. and back to Saudi Arabia while a government-imposed ban on air travel was in effect, all without any intervention by the FBI, has since been negated by the National Commission on Terrorist Attacks Upon the United States (also known as the “9/11 Commission”). In their final report, the commission noted:

Three questions have arisen with respect to the departure of Saudi nationals from the United States in the immediate aftermath of 9/11: (1) Did any flights of Saudi nationals take place before national airspace reopened on September 13, 2001? (2) Was there any political intervention to facilitate the departure of Saudi nationals? (3) Did the FBI screen Saudi nationals thoroughly before their departure?First, we found no evidence that any flights of Saudi nationals, domestic or international, took place before the reopening of national airspace on the morning of September 13, 2001. To the contrary, every flight we have identified occurred after national airspace reopened. Second, we found no evidence of political intervention. We found no evidence that anyone at the White House above the level of [National Security Council official] Richard Clarke participated in a decision on the departure of Saudi nationals … The President and Vice President told us they were not aware of the issue at all until it surfaced much later in the media. None of the officials we interviewed recalled any intervention or direction on this matter from any political appointee. Third, we believe that the FBI conducted a satisfactory screening of Saudi nationals who left the United State on charter flights. The Saudi government was advised of and agree to the FBI’s requirements that passengers be identified and checked against various databases before the flights departed. The Federal Aviation Administration representative working in the FBI operations center made sure that the FBI was aware of the flights of Saudi nationals and was able to screen the passengers before they were allowed to depart. The FBI interviewed all persons of interest on these flights prior to their departures. They concluded that none of the passengers was connected to the 9/11 attacks and have since found no evidence to change that conclusion. Our own independent review of the Saudi nationals involved confirms that no one with known links to terrorism departed on these flights.
