Fistfight Broke Out on a Flight from Tokyo to L.A.

Two guys on a flight from Tokyo to Los Angeles got into a FISTFIGHT before their flight took off Monday night.  One looks like he's in his 20's or 30's.  The other one was an older guy in a red Hawaiian shirt.  Apparently he started it.   

A passenger behind them got part of it on video.  He says the guy in the red shirt asked the other guy where he was from . . . then immediately said, "I'm going to KILL you" and attacked him.  It's not clear if he was drunk or what.   

A female flight attendant tried to break it up.  Then the guy with the camera stopped recording and stepped in.  The one who started it got taken off the plane, and that's the latest we've heard.
