Watch: Explosive fist fight on plane between passengers going from Narita to LAX

It's not just security and airline staff you've gotta watch out for on planes these days. Here's an aggressive fight between two passengers on an ANA Japanese flight from Narita to LAX. The flight hadn't yet taken off when the men started pummeling each other.

"Someone help, this guy is crazy!" one of the men screams. You can also hear one of them shouting, "Get this guy off this plane!"

Passengers are begging them to stop while a baby cries and a flight attendant tries to break it up. It quiets down for half a minute, then starts back up.

According to the Daily Mail, one of the men - a 44-year-old American - was drunk. When the airline asked him to get off the plane, he became even surlier.

According to Japan Today:

Deeming him a potential safety threat, the airline decided to ask him to disembark before takeoff. However, the man resisted, hit a woman passenger and after leaving the plane, proceeded to choke a male airline employee, which led to his arrest.

Have plane rides always been this crazy, or is it something in the air?
