A pilot made an emergency landing after a fight broke out over a passenger who allegedly refused to stop passing gas.

Two Dutchmen sitting next to the flatulent passenger reportedly asked the man to stop, but he refused and continued to break wind aboard the Transavia Airlines flight from Dubai to Amsterdam Schiphol.

The budget airline crew allegedly did not help the passengers after their complaints, Metro reports, leading to a fight between the men. Despite a warning from the pilot, the altercation continued and forced the airplane to be diverted to Vienna Airport, where it made an emergency landing.

Police boarded the plane once it landed and removed two women and two men whom the pilot reported as “passengers on the rampage,” Metro reports.

The women, who are sisters, who were removed from the flight are now taking the airline to court, claiming they were not involved in the alternation. Nora Lacchab, a 25-year-old law student, called the removal “humiliating.”

“We had no idea who these boys were, we just had the bad luck to be in the same row and we didn’t do anything. All I will say is that the crew were really provocative and stirred things up,” Lacchab said to De Telegraph.

All four passengers were released from police custody without being charged. However, all have been banned from flying Transavia Airlines in the future.

“Our crew must ensure a safe flight. When passengers pose risks, they immediately intervene. Our people are trained for that. They know very well where the boundaries are. Transavia is therefore square behind the cabin crew and the pilots,” the airliner said in a statement.
