Planes operated by several US airlines are being ordered to stay in the air due to major worldwide IT outages.
The American air regulator said American Airlines, Delta Airlines and United Airlines requested a ‘global ground stop’ in the early hours on Friday.
This means pilots in the air will be told not to land, while planes on runways cannot take off.
Businesses worldwide have warned of disruption to their services, including Sky News and numerous UK rail operators, with many blaming third-party systems.
Downed services include Microsoft’s entire cloud service, which huge numbers of firms rely on across the globe, though the company says that outage has been resolved.
