The video you see above is of Austrian police escorting 4 Dutch passengers off of a flight from Dubai to Amsterdam. The reason...flatulence.

On a Transavia flight, one of the passengers kept passing gas. It was so bad that an altercation broke out between the one who dealt it and the ones who smelled it. Since a fight broke out on the flight, the pilots were forced to make an emergency landing in Vienna, Austria.

The four Dutch citizens, two male and two female, were escorted off the plane because according to Transavia:

the "unruly passengers" could pose a hazard to flight safety.

This is something that definitely doesn't happen every day.
