Visible work and unseen work reinforce each other.
The archive reflects the organization as it existed when Mission Hall was produced. Titles and responsibilities can change, but the underlying functions remain instructive.
Transportation Security Officers
Use screening procedures and technology to identify prohibited and dangerous items while moving large numbers of travelers through airports.
Federal Air Marshals
Work within the aviation system to deter and respond to criminal violence, aircraft piracy, and other threats to passenger flights.
Transportation Security Inspectors
Conduct inspections, investigations, and compliance work across regulated transportation entities and modes.
Canine teams
Pair trained dogs with handlers to detect explosive odors and support screening and threat-assessment operations.
Explosives specialists
Bring technical knowledge to threat assessment, field education, operational support, and vulnerability review.
Federal Security Directors
Coordinate people, processes, technology, partners, and daily security operations within the airport environment.
Public service
Protecting movement is an everyday act.
The uplifting center of this history is not any single leader or technology. It is the sustained, often unseen work of people who accept responsibility for travelers they may never meet again.
