151:(TSA) was introduced to take over all of the security functions of the country's airports. The TSA increased the number of security agents employed from 16,200 to 56,000 and increased their compensation. In addition, they reformed the training for these agents. Prior to 9/11, the security staff was generally undertrained with a reported training time of 12 hours prior to 9/11; afterwards, this training was increased to more than 100 hours. They also implemented verification tests of the training by projecting images of banned objects on machines to see if workers would be able to identify them. The actual process of security screening was revised as well after 9/11. Passenger pre-checks became standard and the percent of baggage screened for explosives increased from an approximate 5% to 100%. In some countries, for example, Sweden, Norway, and Finland, there were no or only random security checks for domestic flights prior to 09/11/2001. On or quickly after September 11, decisions were made to introduce full security checks there. It was immediately implemented where possible, but took one to two years to implement everywhere since terminals were often not prepared with room for it. The TSA also introduced changes on the airplanes themselves, including bulletproof and locked cockpit doors and air marshals which became standard on commercial passenger aircraft.

FFA. CAPPS flagged 6 of the 19 terrorists that were part of the attacks in 2001. The concern with CAPPS was that it also flagged 65,000 other passengers that day. Many
Americans viewed this as a threat to their privacy and their information. CAPPS II was created post 9/11 and was created for the same purpose of preventing terrorist attacks and ensuring the safety of Americans. Many Americans had issues with CAPPS II because they believe that it racially and politically profiled passengers. In 2004, the TSA was delayed in testing and developing CAPPS II because they could not obtain passenger data because of privacy concerns.
135:, there was an immediate call to action regarding the state of aviation security measures as the hijackers involved in 9/11 were able to successfully pass through security and take command of the plane. The existing security measures flagged more than half of the 19 hijackers in 9/11; however, they were cleared to board the plane because their bags were not found to contain any explosives. In the months and years following September 11, 2001, security at many airports worldwide were reformed to deter similar terrorist plots.

Air security and restrictions after the

Some countries also fingerprint travellers or use retina and iris scanning to help detect potential criminals, although this is predominantly in relation to detection of immigration violations by inbound passengers rather than security checking of outbound passengers.
