High Quality Content by WIKIPEDIA articles! The No Fly List is a list, created and maintained by the United States government`s Terrorist Screening Center (TSC), of people who are not permitted to board a commercial aircraft for travel in or out of the United States. The list has also been used to divert away from U.S. airspace aircraft not flying to or from the U.S. The number of people on the list rises and falls according to threat and intelligence reporting. As of 2011, the list contained about 10,000 names. The list – along with the Secondary Security Screening Selection, which tags would-be passengers for extra inspection – was created after the September 11 attacks in 2001.
