When Your GPS Is Lying: Aviation's Spoofing Problem

Aircraft are being fed counterfeit satellite signals that produce a confident, wrong position — with no red lights, no master caution, and no checklist. This episode unpacks the difference between jamming and spoofing, the hybrid IRS trap on the 787 and G650, and the manual alignment trick crews use at Larnaca, Tel Aviv, and Beirut. From the Vilnius aborts at 850 feet to FlySafe's finding that the Middle East accounts for over 68% of global GNSS interference events, we trace how a timing system disguised as a navigation system became one of aviation's hardest operational problems — and what a listener's airport sign question taught us about independent reality checks.
