The cause of a key system outage that triggered nationwide chaos at airports after all flights were grounded on Jan. 11 has been revealed by the Federal Aviation Administration (FAA).
Transportation Secretary Pete Buttigieg had indicated that no malign actors caused the system to go down but told news outlets that officials can’t rule it out. However, the FAA issued a statement later on Jan. 11 indicating that the outage was caused by an internal system error.
