US Homeland Security Secretary Markwayne Mullin said in an interview with Fox News that he does not expect layoffs due to the widespread disruption of air travel on November 13. According to RBC, the official attributed the incident with a 98% probability to an attempt to use a 50-year-old air traffic control system under modern conditions. Earlier, due to a communication glitch, the US Federal Aviation Administration (FAA) suspended flights across the country for more than four hours, leading to the cancellation of more than 10,000 flights.
