Yahoo News's live-updates coverage of the nationwide FAA ground stop says airlines canceled thousands of flights Saturday, Nov. 14, as they recovered from Friday's more-than-four-hour halt — the longest since 9/11 — with Transportation Secretary Sean Duffy blaming a router that flooded the system during contractor L3Harris's copper-to-fiber work and officials seeing no sign of a cyberattack. The article also covers Duffy's calls for tens of billions in air traffic control funding, Gov. Kathy Hochul's demand he resign, Sen. Tammy Duckworth's push for an investigation, airlines' travel waivers, and refunds for stranded travelers.
