THE UNITED STATES LIFTS THE FLIGHT SUSPENDED

After more than four hours of paralysis, the United States reopened its airspace following a communications outage affecting several air traffic control centers. The failure, attributed to aging computer equipment dating back to the 1980s, resulted in thousands of delays and more than 6,000 flight cancellations. Authorities have ruled out a cyberattack and excluded any connection to the recent Microsoft outage. However, a return to normal operations is expected to take some time.
