A Ryanair flight from Belgium to Malta was forced to divert to Pisa, Italy, on November 3, after a fight broke out mid-air. Passenger Tommy Engerer shot this video, which shows two men throwing punches at each other, while crew and passengers try to calm and contain the situation.

The Times of Malta, citing Engerer, reported that “the fight was between two men and their respective female partners.”

Later in the video, the pilot can be heard telling the plane that the situation was “not acceptable at all,” and announcing that the flight would be diverted to Bologna, Italy. It was eventually diverted to Pisa, where police arrested the four people involved in the fight, according to reports citing a Ryanair spokesperson. Credit: YouTube/Tommy Engerer
