Fifteen passengers brawled on board Gol Airlines flight 1659 from Salvador to São Paulo in Brazil prior to departure.

Reportedly they were two families. A mother asked for her special needs child to sit in the window seat, but the woman who was already there refused to move. One of the children heard something offensive from the family that refused to move, according to a contemporaneous account on Twitter. And things descended into chaos.

One crewmember offered,

I was already closing the doors when I saw the two slapping each other in row 20. I ran, as soon as I got there, I already got between the two, but what happens: One family had five people and the other 10. The two families started slapping each other, cursing each other.

While the flight was delayed two hours, the airline managed to calm the situation and escort the brawling groups off the aircraft.
