The Transportation and Security Administration was born out of the 9/11 national tragedy. The TSA marked the 10th anniversary at Lambert-St. Louis International Airport on Wednesday, September 12. The STL team, headed by Federal Security Director William Switzer, consists of 450 people responsible for the day-to-day screening of passengers at Lambert at three checkpoints. The TSA screened more than 6.5 million people in 2011.

During the TSA's anniversary celebration, Switzer and Airport Director Rhonda Hamm-Niebruegge both highlighted the importance of the partnership between the Airport and the TSA in running effective, efficient operations with a mission to make air travel safe.
