History of TSA

Following the September eleventh attacks, a pervasive sense of uncertainty engulfed the nation.
A shocked populace anxiously awaited news of potential further attacks.
Airports were shut down, leading to a complete standstill in travel and commerce.
The situation effectively brought operations to a halt across various sectors.

In response to the crisis, Congress sought to restore public confidence in travel.
On November 19, 2001, Congress passed the Aviation and Transportation Security Act.
- This act mandated:
  - All airport screenings to be conducted by federal officials.
  - 100% screening of checked baggage.
In 2003, the Transportation Security Administration (TSA) transitioned from the Department of Transportation into the newly created Department of Homeland Security.
The TSA was charged with the overarching goal of safeguarding the nation's transportation systems.

TSA continuously evolved in response to increasingly complex transportation security challenges.
- 02/2001: After the shoe bomb attempt by Richard Reid, TSA implemented enhanced footwear screening procedures.
- 02/2006: Further recognizing persistent threats, the TSA required all passengers to remove shoes during screening processes to check for explosives.
That same year, a thwarted plot involving liquid explosives carried by terrorists on transatlantic flights led to significant changes:
- TSA banned all liquids in carry-on bags.
- Introduction of the three one one rule for liquids, which allowed passengers to bring a limited quantity in carry-on luggage.

02/2009: An attempted bombing by Umar Farooq Abdulmutallab on a flight from Amsterdam to Detroit prompted:
- The installation of hundreds of advanced imaging technology units (full-body scanners) at U.S. airports, designed to detect non-metallic weapons and explosives.
Over the years, TSA has continued to adapt its security measures to counter emerging threats, including:
- Enhancements to pat-down procedures.
- Raising the baseline of aviation security for international flights entering the U.S.
- New divesting procedures for items in passengers’ carry-on luggage.

As TSA approaches its second decade, it remains an agile national security agency, focusing on:
- Investing in new technologies to bolster security,
- Rapid deployment of capabilities to combat threats,
- Commitment to public safety and service.
Since its inception in February 2001, TSA has consistently emphasized the importance of its personnel, recognizing that the agency's greatest asset is the dedicated men and women executing its mission.
TSA is poised to move forward with a renewed commitment to both its staff and the public they serve, continuously looking to outpace evolving threats.
