The Federal Aviation Administration rescinded its nationwide ground stop on Friday evening following widespread radar and communications failures at regional control centers. Transportation Secretary Sean Duffy and Homeland Security Secretary Markwayne Mullin clarified that an influx of data into legacy systems caused the breakdown rather than a cyberattack. Aviation analytics firm Cirium reported that roughly 500 of the 600 diverted flights had to turn around and return to their origin airports. Normal air traffic patterns are expected to recover gradually after the disruption scrambled schedules for over 1.5 million travelers.
