You mean these flights?
From Newsweek:
Saudi flights out of the United States. The movie claims that in the days after 9/11, when airspace was shut down, the White House approved special charter flights so that prominent Saudisâ??including members of the bin Laden familyâ??could leave the country. Author Craig Unger appears, claiming that bin Laden family members were never interviewed by the FBI. Not true, according to a recent report from the 9/11 panel. The report confirms that six chartered airplanes flew 142 mostly Saudi nationals out of the country, including one carrying members of the bin Laden family. But the flights didn't begin until Sept. 14â??after airspace reopened. Moreover, the report states the Saudi flights were screened by the FBI, and 22 of the 26 people on the bin Laden flight were interviewed. None had any links to terrorism.
