The skies above us are busier than ever, with thousands of aircraft crisscrossing the globe every day. Ensuring the safe and efficient movement of these aircraft is a monumental task, one that falls to air traffic control (ATC). Mid-air collisions, though rare, are among the most catastrophic risks in aviation. Thanks to the meticulous work of air traffic controllers and the sophisticated systems they use, the likelihood of such incidents has been drastically reduced. This article explores how air traffic control prevents mid-air collisions, even in the most crowded skies. A high-tech air traffic control tower managing busy airspace, using advanced radar, ADS-B, and communication systems to prevent mid-air collisions and ensure aviation safety. The Challenge of Crowded Skies Modern aviation operates on an unprecedented scale. In 2023, the global aviation industry handled over 40 million flights, with peak times seeing thousands of aircraft in the air simultaneously. The chall...
