Vintage photos show what airport security was like before 9/11
Flying used to be far more relaxed. In the aftermath of September 11, airport security transformed almost overnight.
Air travel security has undergone significant changes since the 1970s, with the system becoming far more stringent following the 9/11 attacks. Before 9/11, the Transportation Security Administration (TSA) did not exist and private companies handled airport screenings. Knives and other blades were permitted in carry-on bags as long as they were under 4 inches in length, and passengers did not need plane tickets to enter security.
X-ray baggage screenings were introduced in the 1950s, but these were far less sophisticated than today's systems.
In the 1970s, security measures ranged from manual searches to the use of magnetometers and X-ray machines. There were separate lines for passengers without carry-on luggage, and even life insurance vending machines for nervous flyers. However, passengers could still bring liquids and gels in their bags, and there were no specific restrictions on bringing personal items like knives or box cutters.
The first security lines at San Francisco International Airport appeared in 1973, featuring walkie-talkies for communication and sticks for bag inspections. By the mid-1970s, the Federal Aviation Administration mandated the use of magnetometers and X-ray machines to prevent hijackings, and full-body scanners would not arrive until 2007. The era before 9/11 highlights the dramatic evolution of airport security in response to various threats, ultimately leading to the robust system in place today.
