As the Federal Aviation Administration rolled out its cutting-edge AI-powered SMART platform designed to modernize air traffic management, a crippling electrical circuit failure struck New York airspace on Monday, September 21, 2026. The technical malfunction caused a complete ground stop at John F. Kennedy International, LaGuardia, and Newark Liberty airports, cutting off critical radio and radar equipment at a single point of failure. Compounding the crisis, officials discovered that a newly built fiberoptic backup system had been accidentally damaged by construction work, leaving the multi-airport network scrambling for fixes as delays mounted across the national airspace system.
