According to reports, an airline had to make an emergency landing after a fight broke out onboard over a passenger who allegedly wouldn’t stop passing gas.

It has been reported that two passengers on the Transavia Airlines flight from Dubai to Amsterdam Schiphol asked the man who was passing gas to stop, and he refused. Allegedly, the flight crew did not help the passengers after they complained and it led to a fight between the men.
