Nearly 8,000 flights were canceled in the US due to a communication glitch.
The hour-long flight ban imposed by the American authorities has already been lifted - domestic flights to the United States have been allowed to take off again, writes CNN.
Transport Minister Sean Duffy blamed the incident on outdated air traffic control technology. He warned of more failures if the system is not upgraded.
US Homeland Security Secretary Markwayne Mullin pointed to the FAA's upgrades to these outdated systems as the reason for the grounding. He added that the flight ban was not caused by any threat to the United States and is not related to this week's massive shutdown at Microsoft.
CNN also notes that the aviation chaos erupted a week after the Federal Aviation Administration announced it would phase out floppy disks.
