A Transportation Security Administration officer helps safeguard the public by evaluating travelers and their cargo before they board commercial American airplanes. TSA agents are trained to operate X-ray machines and hand wands at airport screening checkpoints.
TSA officers also facilitate the flow of passengers through the security checkpoints and maintain communication with direct supervisors. TSA officers work at about 400 commercial airports. The TSA is a branch of the U.S. Department of Homeland Security. Two months after the attacks of Sept. 11, the 107th Congress passed the Aviation and Transportation Security Act, which created the new department to protect travelers.
