This is the terrifying moment a plane passenger tried to open an emergency exit in mid-flight.
The man, in his 50s, was on Fuzhou Airlines flight 6509 from Fuzhou to Kunming, in southwest China, on May 20.
Flight security officer Zhao Wenhui told The Strait Metropolitan that the man requested help from cabin crew about 40 minutes before landing.
He asked to call his family but became agitated when his request was denied.
Mobile phone footage shows the man yelling and banging seats and the side of the plane as a flight attendant and other passengers tried to restrain him.
Crew member Cao Xinyue said: "After that the man started pacing back and forth saying: 'I want to parachute!'
"He kept saying he wanted to call his family.
"He tried to make a call on his phone but asked us to do it when his phone didn't work."
Horrified passengers can be heard shouting "what's going on?" as they tried to calm the man.
However, 10 minutes before landing he allegedly sprung from his seat and tried to open emergency door, the airline said in a statement.
The group held him down until the plane landed safely, after which he was handed over to Kunming airport police.
Flight attendant Lu said: "He tried to gouge my eyes. I'm taller than him so he didn't manage to reach, but my ear and nose were hurt and bleeding."
Flight security officer Zhao, who spent two years with China's special forces task force known as the Snow Leopard Commando Unit, said he noticed the passenger acting erratically as he boarded the plane.
The airline confirmed no other passengers were hurt.
The man, who police say was unwell, has been released without charge back into the care of his family, who have apologised for the ordeal.
It is unclear, however, whether he will receive a lifetime flying ban by China's aviation authority.
