A meth-addled plane passenger tried to open the emergency door as the flight soared over the Pacific Ocean on Thursday, according to local reports.

The 26-year-old woman was arrested by the Incheon International Airport Police Corps after trying to yank open the door of the Korean Air flight traveling to Incheon, a South Korean city bordering Seoul, Yonhap News Agency reported.

The plane had been nearing the end of its 15-hour flight from New York that had departed at 2 a.m. the previous day.

Witnesses told police she had begun showing signs of anxiety about 10 hours into the flight and tried to rip the door open several times before she was finally restrained by flight attendants.

She later tested positive for meth, airport officials told the Korea JoongAng Daily.

Police said the woman had entered the country after staying in New York for over six months, and had no record of mental illness.

It is the third instance of a passenger trying to open emergency doors on Korean flights this year, including a drugged-up 19-year-old who was sentenced to three years in prison.

It also comes one month after an Oregon off-duty pilot allegedly tried to down a max-capacity plane while experiencing a days-long mental breakdown exasperated by a magic mushroom trip.

Joseph Emerson — who faces a count of attempted murder for each of the 83 lives on board — claims he thought he would snap out of his drug-induced delusional state if he crashed the packed plane.
