Things took a turn for the worse Tuesday onboard a flight from Tokyo to Los Angeles.
As passengers began to settle in for the 11-hour stretch, a confrontation between two male travelers came to blows after one of them suddenly became irate.
"No one provoked him — he was cool up until a few minutes before he started hitting the guy," passenger Corey Hour, who filmed the fight, reportedly told CNN. "He started verbally abusing and intimidating people. Nothing triggered him, it just happened."
The All Nippon Airways flight became a boxing ring as the men threw punches in what was deemed an “air rage” incident.
"The airline staff did what they could to diffuse the situation, and they reacted appropriately," Hour said. "There were children everywhere, you can hear in the video them crying.”
The man being attacked can be heard shouting, “Someone help, this guy’s crazy,” while the attacker threatens, “I’ll kill you.”
Hour, who is from Phoenix, Arizona, said he eventually stopped recording and intervened when the aggressor wouldn’t back off his target. Even after briefly walking away, he came back to fight some more.
“I was the one who stepped in. He backed down, I squared up with him and he wouldn't confront me," Hour recounted.
Eventually, the man was escorted off the flight by airline staff, but the flight was delayed by more than 90 minutes as a result of the ordeal.
After the chaos, the airline released a statement apologizing for the inconvenience of the delay.
“All Nippon Airways apologizes to our passengers on Flight#6 to Los Angeles for the pre-flight incident,” the statement said. “The individuals involved have been dealt with appropriately by local law enforcement.”
One thing's for sure, the high altitudes certainly can't be blamed for causing the traveler to lash out, considering he initiated the attack before the plane even took off.
