From CBS news: An elderly man on an American Airlines flight was restrained by passengers, including television's "Dr. 90210," after he got out of his seat and shoved a flight attendant late Monday, officials said.
Dr. Robert Rey, a plastic surgeon who practices martial arts, told The Associated Press he got out of his seat and intervened when he heard the man make a "big noise" as he pushed a female flight attendant toward the cockpit.
"When you get a black belt, at that stage your brain just clicks into action," the doctor said. "I restrained this gentleman in a very aggressive way without hurting him."
Of course the story continues with this:
Flight crew members described the man as "very frail".
