It seems the 29-year-old woman had been drinking heavily due to her boyfriend breaking up with her just before she boarded the flight. Footage shows the flight attendants trying to comfort the crying woman, known by her surname Li, who suddenly started hitting the cabin window until it cracked at 30,000 feet.

The plane had to make an emergency landing and Li was detained by Henan police for damaging public transportation. It remains unclear what type of punishment she would face, but such an offence could result in a jail sentence between three to ten years, according to Chinese laws.
