Yesterday's ground stop after a telecom glitch forced airlines to cancel thousands of flights across the country.
The disruption, which briefly activated the White House Situation Room and FBI investigators, was traced to an L3Harris contractor's fiber-optic upgrade that flooded air-traffic control routers with over 1,000 connection attempts per second.
FAA Administrator Bryan Bedford confirmed the system recovered after the faulty network was isolated, and Transportation Secretary Sean Duffy warned the contractor will be held accountable for the service lapse.
The incident occurred on Nov. 13, prompting a multi-hour halt that was later attributed to a maintenance error rather than a cyberattack.
