The Australian Transport Safety Bureau (ATSB) said Flight QF72 had experienced a “sudden in-flight upset” while cruising in “level flight.”

“The crew diverted the aircraft to Learmonth, near Exmouth in WA, where it landed without further incident,” the ATSB statement concluded.

Sergeant Greg Lambert told Australia’s AAP news agency that the plane landed safely after making a mayday call.
