An elderly passenger tried to open the door of a Boeing 787 while it was flying over the Atlantic Ocean

• An elderly passenger tried to open a plane door above the Atlantic Ocean, police said.
• He wasn't charged as police determined he was "in a state of crisis and confusion."

An elderly man tried to open a plane door while flying over the Atlantic Ocean, Canada's CityNews reported.

Another passenger on board Sunday's Air Canada flight from London to Toronto told the outlet he was "acting strange" throughout the journey.

They added that the pilot told everybody to stay in their seats upon landing.

Officers from the Peel Regional Police boarded the Boeing 787 Dreamliner after it landed in Toronto and spoke to the man, but decided not to press charges.

"The passenger, an elderly male, had been in a state of crisis and confusion and it does not appear that his actions were intentional," Constable Tyler Bell-Morena said in a statement to CityNews.

"No criminal charges have been laid, the man and his family have been connected with additional resources."

Emergency doors on commercial aircraft are designed to be impossible to open at high altitudes. They're sealed shut because the cabin pressure is much higher than the outside air pressure.

It's the third peculiar incident on board an Air Canada flight this month.

Two weeks earlier, a passenger boarded a Boeing 777, opened a door, and fell out of the plane onto the tarmac.

And on January 3, a flight to Calgary was diverted after police said a 16-year-old assaulted a family member.

Although, unlike those incidents, Sunday's flight was able to continue to its destination without delay.

In a statement, Air Canada said: "Our crews are experienced and managed the situation appropriately, allowing the flight to continue normally to its destination."
