U.S. Transportation Security Administration (TSA)

The Transportation Security Administration (TSA) is a U.S. government agency responsible for securing the nation's transportation systems, primarily airports and airlines. It conducts security screenings of passengers and baggage to prevent dangerous items from being brought onboard aircraft. TSA staff use various tools such as metal detectors, X-ray machines, and behavioral observations to identify potential threats. Their goal is to ensure safe and efficient travel while respecting passengers’ rights. Established after 9/11, the TSA plays a vital role in national security, balancing security measures with the need to facilitate air travel.
