Flight QF122, a Boeing aircraft, departed the alpine ski town just before 3:30pm on Saturday and was scheduled to land at Sydney's Kingsford Smith Airport at 4:50pm. Footage provided to the ABC shows the plane's left engine emitting flames as it climbed above New Zealand's South Island.
A Qantas spokesperson confirmed the incident was a "suspected engine issue" and said the aircraft was cleared for a priority landing at Christchurch. "Our pilots are highly trained to manage situations like this and the aircraft landed safely," they said, adding that both engines remained operating throughout, with no engine shutdown or failure experienced.
In new details reported by the Guardian via Australian Associated Press, passenger Liza-Jayne Loch, who was returning home from a business trip, described the moment the flight ran into trouble. "There was a loud bang," she said, recalling the cabin lights flickering and hearing "a lot of screaming" as the plane climbed above the South Island's mountain ranges.
Liam Aspinall, who filmed the flames from the ground in Queenstown, told the ABC he noticed the flames approaching from a distance. "I noticed flames appearing to come off the thing as it was approaching us from afar," he said. "Sounded like gunshots, [it] was loud."
Support is being provided to passengers, the Qantas spokesperson said, in recognition of what "would have been a distressing experience." Passengers are being offered accommodation and help with alternative flights.
The incident comes after a previous Qantas flight from Queenstown to Sydney experienced a similar diversion due to an engine issue, though no further details on that earlier event were provided in source material.
