A man tried to storm the cockpit and open a plane's door during a flight as terrified passengers watched in horror.

He made an announcement, telling everyone to be close to their oxygen masks before he headed towards the door, an eyewitness said.

The pilot asked all "strong men" to come forward and deal with the emergency, the Daily Star reports.

The Delta flight was travelling from Los Angeles International Airport to Hartsfield-Jackson Atlanta International Airport, but was diverted to Oklahoma City Airport due to the incident.

A passenger shared the terrifying footage on Twitter, writing: "Someone tried hijacking our plane from LAX to ATL."

In the video, several passengers and staff can be seen trying to restrain the man near the plane's door, as other people scream and shout, asking him to stop it.

As the plane was diverted to Oklahoma, the passenger was handed over to law enforcement officers.

They also carried out a search of the plane to rule out any “further security issues”, according to eyewitness Benjamin Curlee.

A spokesperson for Delta said: "Thanks to the crew and passengers of Delta Flight 1730 who assisted in detaining an unruly passenger as the flight diverted to Oklahoma City (OKC).

"The aircraft landed without incident and the passenger was removed by law enforcement.

"We apologize to our customers for the delay and any additional inconvenience this caused."

In February this year, three people died in a plane crash in the US shortly after take-off.

A Cessna 182 flight was bound for Florida and had just taken off from north Georgia when it crashed into a wooded ravine.

According to US media, the pilot was trying to turn the plane around and head back to the airport when the crash near Gainesville occurred.

Gainesville Fire Department Division Chief Keith Smith said: "The plane did leave from Gainesville and we confirmed they were en route to Daytona Beach.

"And speculation at this point, but [the pilot] turned around for some reason and tried, apparently, to get back to the airport."
