The security measures and screening procedures at U.S. airports have been significantly transformed over the past 25 years, largely in response to terrorist attacks. Prior to 9/11, security was managed by private contractors and was less stringent, allowing items like knives and larger liquids. The 9/11 attacks, carried out by Al-Qaeda, led to the creation of the Transportation Security Administration (TSA), federalized passenger screening, reinforced cockpit doors, and mandatory 100% checked baggage screening. Earlier attacks, such as the bombing of Pan Am Flight 103, also prompted changes, particularly concerning checked baggage and the detection of explosives. AI
