Corey Hour, who shared the fight on social media, said that 10 before take off one of the passengers started the fight in the row in front of him.

"No one provoked him -- he was cool up until a few minutes before he started hitting the guy," Hour told CNN. "He started verbally abusing and intimidating people. Nothing triggered him, it just happened."

He yells, "You think I'm crazy? What about the government!" Then exits the plane. 1.5 hours later and we finally take off.  jfc

Hour said at one point the man in the red shirt walked away only to come back and starting hitting the other passenger again, which is when Hour decided to get involved.

The video ended when I stepped in & confronted the man in the red shirt. I told him to leave and squared up with him, he backed down n left.

As of now and after speaking with the other passengers the motive for why he did this is still UNKNOWN. None of us have any idea why at all.
