Greece Air Traffic Radio Failure Grounds Flights, Stranding Thousands

• A major technical failure in Greece's air traffic control system, specifically a collapse of central radio frequencies, grounded flights nationwide.
• Thousands of travelers were left stranded at airports, including Athens' Eleftherios Venizelos, after services came to a standstill early Sunday.
• Panagiotis Psarros, Chair of Greek Air Traffic Controllers, stated all frequencies were lost, preventing communication with aircraft, and blamed "ancient" equipment.
• The disruption primarily affected the Athens and Macedonia area control systems, overseeing the vast Athens Flight Information Region.
• Over 75 flights were delayed, and Israel's Airports Authority advised travelers to expect delays due to Greek airspace closure until 4 p.m. local time.
