Passengers on a Qantas jet flying over  Australia got a shock when they spotted a 12ft python clinging on to a wing at  30,000ft.

The plane was around 20 minutes into its  flight from Cairns in northern Australia to Papua New Guinea when a female  passenger first announced she could see the reptile.

Those on board could only watch as the snake  - thought to be a Scrub Python - spent the flight battling to survive in  freezing conditions.
