OSINT deep-dive: FAA nationwide grounding caused by long-haul ATC comms, radar and GPS fine
eigenrobot · x · 2026-11-14
An independent OSINT check during the nationwide FAA grounding found radar, GPS and weather sensors all working — the failure was in the long-distance communications network that lets the FAA's 22 regional Air Route Traffic Control Centers talk to high-altitude aircraft and hand them off. The post explains the ATC architecture: towers only handle takeoffs/landings and nearby airspace; ARTCCs manage regional cruising traffic, normally isolated so one center's failure shouldn't cascade nationwide.
