An ABC news article reports that Australians were caught up in widespread US flight disruptions after a telecommunications outage forced the Federal Aviation Administration to issue its first nationwide ground stop since January 2023, delaying or cancelling more than 11,000 flights. Stranded travellers include Trish Crabb, whose Delta flight out of JFK was cancelled, and Rivkah Brown, stranded in San Diego, who now plans a nearly 10-hour bus ride to Las Vegas. Officials, including Homeland Security Secretary Markwayne Mullin, say there is no indication of a deliberate attack, and Australian travellers due to fly within 72 hours are urged to contact their airline or travel agent.
