San Antonio International Airport - regional aviation technology hub

San Antonio International Airport (SAT) has served commercial and military aviation needs since the World War II era and grew into a regional transportation and aviation-technology center in the mid-20th century. The airport's control tower, radar installations, and airfield systems were part of broader developments in air traffic control and navigation technology in the region. SAT remains the primary commercial airport for San Antonio and reflects successive generations of aviation infrastructure upgrades.
