What significant change did the Aviation and Transportation Security Act of 2001 enact?

The Aviation and Transportation Security Act of 2001 marked a pivotal moment in U.S. aviation security by creating the Transportation Security Administration (TSA). Following the September 11 attacks, there was a critical need to enhance the security protocols surrounding air travel. The establishment of the TSA allowed for a unified federal oversight of security measures across all airports, ensuring a consistent approach to screening passengers and baggage.

This change was instrumental in addressing vulnerabilities in the aviation system and incorporated comprehensive security measures, such as the implementation of stricter screening processes and background checks for airport personnel. The formation of the TSA represented a shift towards greater federal involvement in transportation security, reinforcing public confidence in air travel safety.
