Why Pilots Are Turning Off Their GPS Mid-Flight

In an era where we take precision navigation for granted, the invisible infrastructure of the sky is under attack. Global positioning system (GPS) jamming and "spoofing"—the act of sending deceptive signals—have surged across Eastern Europe and the Middle East, turning routine commercial flights into high-stakes navigation challenges. This episode dives into the technical mechanics of electronic warfare and explains why a satellite signal is as fragile as a whisper in a crowded stadium. We explore the terrifying reality of cockpit "terrain" warnings triggered by fake data and the life-saving backup systems pilots use when their primary tools fail. From the resurgence of 20th-century radio beacons to the self-contained precision of laser gyroscopes, learn how the aviation industry is adapting to a world where the ground beneath a plane isn't always where the instruments say it is. It’s a deep dive into the "digital shields" protecting cities and the collateral chaos they create for the three hundred tons of aluminum and passengers flying overhead.
