DALLAS – Passengers rallied to restrain a disruptive passenger in a seat on a flight from Milwaukee to Dallas–Fort Worth on Tuesday after trying to open a plane door while in the air.

The FBI is investigating the incident on American Airlines flight 1915, but no charges have yet been filed against the Canadian man.

According to an incident report, the unruly passenger made several comments to a flight attendant and then demanded to get off the flight, lunging at the flight attendant and one of the plane’s doors.

Doug McCright from McKinney was on Tuesday’s flight from Milwaukee to DFW. He remembers seeing a man talking to a flight attendant near his row at the front of the plane.

“I could tell the conversation wasn’t going very well,” he recalled.

McCright says the flight attendant asked the man several times to return to his seat, but he ignored her.

McCright says she motioned to his back for help, so he jumped to his feet and spoke to the man.

“I said, ‘Sir, she wants you to go back to your seat.’ You have to go back to your seat,” he recalled. “He turns around and says, ‘I’m getting off this flight! I want to get off this flight!”

According to an incident report, the man rushed the flight attendant and threw himself at the door of a plane, hitting the flight attendant.

McCright says he grabbed him from behind and restrained him.

“We’re 30,000 feet in the air, flying 300 miles an hour. There was no time to think, you just had to do something right now,” he said.

Several other passengers, including Charlie Boris, had the same quick reaction and rushed to the front of the plane.

“The flight attendant coming back said he was trying to open the door and that’s when I kind of went all in,” Boris said.

McCright, Boris and another man taped the man’s hand and legs, then held him down for the last 30 minutes of the flight.

When they landed, DFW Airport police and the FBI were waiting for them.

“It was kind of a fight or flight situation,” Boris said. “And they all really helped out and put in the effort together, and we all get to go to Thanksgiving.”

Something McCright is very grateful for.

“For me, it wasn’t like there was a choice,” he said. “There was no choice. It had to be done.”

The plane landed at DFW Airport shortly after 10am

DFW Airport Police and the FBI boarded the plane as soon as it landed.

A passenger was still kneeling on the disruptive passenger when law enforcement arrived.

The man was wheeled away for a mental evaluation.

The flight attendant injured her wrist and neck during the altercation and had to be taken to hospital. She has since been released.
