An Air New Zealand flight has been caught up in an air drama in Europe.
Air traffic controllers in London have revealed a Boeing 777 suffered a hydraulic system failure.
Fire appliances were on the runway at London's Heathrow Airport to greet Flight NZ-2, after pilots set off an emergency squawk code above Ireland, to alert air traffic control that it needed priority landing.
The Air Traffic Service confirmed that one of the plane's three hydraulic systems had failed.
But the flight from Los Angeles landed safely last night, New Zealand time.
Air New Zealand says there was no actual emergency and says what it calls a "minor technical incident" has been resolved by engineers.
