Ethan Williams was on a Cathay Pacific flight from Hong Kong to Los Angeles when one of the cabins in the aircraft began to fill with smoke halfway through the flight.
The pilot made the decision to make an emergency landing and passengers were told to put on life jackets stored under their seats.
Ethan- and events manager- decided to film the ordeal on his iPhone, later posting the footage onto YouTube.
He spoke into the microphone on his ear phones: "Ok, so I'm not sure what's happening but there's something going on with this flight all the flight attendants are running around like crazy and all the warning signs are going off.”
Ethan then added: "We've just had an announcement, we've got an emergency landing. We've not been told what is going on but we've got an emergency landing."
To the passengers relief, the pilot is heard making an announcement that the plane will land in Los Angeles as planned rather than making an emergency landing into the sea.
The 276 passengers on board the plane can be heard clapping as they hear the news.
After the plane landed safely, Cathay Pacific apologise to travellers and offered $300 compensation.
