Richard Marx subdued a violent passenger on Korean Air Flight

Richard Marx had anything but a relaxing flight as he helped subdue an abusive passenger on Korean Air flight 480.

As originally reported by TMZ, the ordeal was caught on camera and video by Marx's wife, former MTV VJ Daisy Fuentes. A passenger allegedly became violent during the flight, injuring two passengers and a crew member during the attack, which Marx said lasted four hours.

Marx, who aided the flight attendants in taking down and restraining the man, described the crew as "completely ill-trained" and "completely ill-equipped to handle situation," in a series of tweets.
