AI Summary

U.S. officials found no evidence that a cyberattack caused the FAA’s nationwide ground stop on Friday, which was triggered by a communications problem at its air‑route traffic‑control centers. The FAA issued the stop on November 13 and lifted it at 8:15 p.m. ET after more than four hours, disrupting thousands of flights before departures resumed, though delays are expected to linger for several days. Homeland Security Secretary Markwayne Mullin said the failure appeared mechanical, noting no chatter or footprints of hacking, while the FBI continues to examine whether a recent software update may have been involved.
