SAN ANTONIO — More than 200 people gathered Wednesday morning to say goodbye to the last Air Force unit at Brooks City-Base. The 311th Air Base Group was inactivated after serving the USA for nearly a century. In 2005, the Base Realignment and Closure Commission mandated the 311th Human Systems wing be closed by this September. The time has arrived. The Wednesday ceremony was all about honoring Brooks proud heritage of 95 years of service to America. The 311th Air Base Group’s history goes back to January 19th, 1918 when the medical research laboratory opened in New York. Four years later it was moved to Brooks field here in San Antonio. In 1959 the base became the headquarters for the Aerospace Medical Center, bringing scientists and physicians to the Alamo City and laying the foundation for San Antonio’s current bio-medical research sector. As the School of Aerospace Medicine, Brooks played a critical role in advancements that put American astronauts on the moon. It was also what brought President John F. Kennedy to San Antonio on Nov. 21,1963. He dedicated four new buildings in the complex that housed the Aerospace Medical Division. it would be his final act as president. Kennedy was assassinated the following day in Dallas. Brooks Air Force Base was part of the foundation of San Antonio, and now city leaders say it will continue to play a vital role in our future through the Brooks Development Authority.
