The moment a thick white mist began filling the cabin of a Jetstar plane has left passengers baffled - but there's a simple explanation.
The heavy fog-like haze can be seen drifting through the aircraft, limiting visibility and cloaking the cabin in a large white cloud.
The footage, uploaded to social media this week, was taken on a Jetstar flight leaving Bali and sparked a wave of reactions from Aussies.
Many said they had experienced the same phenomenon on other flights.
'My Jetstar flight was like this from Denpasar to Sydney last weekend,' one commenter wrote.
'I've never seen anything like it and thought something was wrong with the plane.'
Another added: 'Ours was the same going from Cairns to Bali.'
'I've experienced this leaving Bali, thought our plane was on fire,' a third said.
'This happened to me on a Vietnam Airlines flight on September 11 last year. I really thought it was the end of me,' fourth added.
One commenter solved the mystery, explaining the mist had been caused by the cold air-conditioning of the plane combining with the humid Bali weather.
'It's just condensation. The dry air from the aircon mixing with the damp humid air from outside,' they wrote.
A Jetstar spokesperson said passengers shouldn't be worried if they saw the mist on future flights in a statement to Daily Mail Australia.
'This fogging happens when warm and humid air mixes with cooler and dryer air from the aircraft air-conditioning system, forming condensation,' they said.
'Customers shouldn't be concerned as it's a common occurrence in hot and muggy environments like Bali and usually clears quickly.'
Speaking to CNN, climate scientist Dr Indrani Roy from the University College London, reiterated that the mystery fog is far less terrifying than it looks.
'The environment on board an airplane creates perfect conditions for condensation in the cabin,' she explained.
She explained that condensations occurs when warm water vapour in the air, which she describes as 'prone to sticking', comes into contact with cooler solid surfaces.
Dr Roy said while the ghostly fog may appear concerning, it's not dangerous.
'Neither mist nor any resulting condensation is cause for alarm,' she said.
