Australian police are questioning passengers to see if anyone was using electronic equipment on-board the Qantas A330-300 which span out-of-control mid-flight last week.
According to the Australian Transport Safety Bureau (ATSB), a computer glitch may have caused the sudden rise and drop in altitude which resulted in the injury of 74 people. While on its way to Singapore, the plane shot up 300ft before plunging downwards before the pilot regained control.
The ATSB hasn't ruled out the possibility that the malfunction was caused by interference from an electronic device such as a laptop. But the Herald Sun reports that Qantas had been warned over potential problems with the A330-330 aircraft.
