Wednesday, the us experienced a technical glitch that caused a nationwide pause in air travel. major airlines such as delta airlines, united airlines, american airlines group inc and southwest airlines were all affected. the federal aviation administration (faa) suggested that the issue was caused by a damaged database file, and a senior government official confirmed that a corrupted file affected both the primary and backup systems of the faa’s notice to air mission system, or notam.
Technical glitch occurred on wednesday and grounded flights across the us for the first time in nearly two decades. president joe biden has called for a full investigation, and the us department of transportation secretary pete buttigieg stated that the faa grounded flights out of an abundance of caution.
Investigations suggest that the glitch was caused by a corrupted file in the notice to air missions system, which provides real-time safety information to pilots. at this time, the faa has not found any evidence of a cyber attack. airlines such as united airlines and delta airlines have offered waivers and good will policies to affected passengers, and aviation tracking site flightaware reported 1,154 delays and 103 cancelled flights on thursday. officials are still working to determine the root cause of the issue.
