Qantas flight makes emergency landing as cabin temp. Soars

At least 50 passengers and crew were treated for heat stress when a domestic flight of the Australian carrier Qantas made an emergency landing at the Sydney Airport after its undercarriage overheated.
QantasLink QF2260, was travelling from Sydney to Lord Howe Island, when it was forced to return to Sydney "due to a technical issue with the air-conditioning system", a spokeswoman for the airline told a local newspaper.
The plane landed at 1.47 PM local time and ambulance crews assessed about 50 passengers for dehydration.
A New South Wales Ambulance spokesman said two female passengers were treated at the scene for dehydration and transferred to hospital, both in a stable condition, Sydney Morning Herald reported.

He was unable to confirm how high the temperatures were or how long the passengers were exposed to the heat.
Reports said that the cabin temperature climbed to almost 40 degrees Celsius onboard the Dash-8 aircraft.
QantasLink operates flights to more than 50 city and regional destinations across Australia and Papua New Guinea.
