A SMART phone, which combusted onboard a domestic flight from the North Coast to Sydney, is the subject of an air safety investigation.
A passenger's mobile phone started to emit dense smoke accompanied by a red glow, on board Regional Express flight ZL319 from Lismore to Sydney on Friday.
A flight attendant reacted and successfully extinguished the red hot Apple iPhone.
A REX spokesperson said the matter has been reported to the Australian Transport Safety Bureau (ATSB) as well as the Civil Aviation Safety Authority (CASA) for investigation and directions.
While the incident is believed to be an isolated occurrence, authorities have warned air travellers to be wary of possible mid-air phone malfunctions when flying.
