A passenger had to be tied down to his seat while a flight was cruising at high altitude due to his erratic behaviour.
The man reportedly tried to force his way inside the cockpit on a flight in China, reports a website.
He had to be restrained by the cabin crew as he was shouting, throwing money into the air and even tried rushing into the cockpit.
It was reported that he repeatedly shouted: "Someone is trying to get me, I want to go into the sky, I opened the sky eye."
The passenger could be suffering from a mental breakdown.
