A woman caused a stir on a Moscow-bound flight recently, after she was filmed using the air vents on the plane to dry her underwear.

In a video that has since been shared widely online, the woman is seen holding it overhead while seated. She moves it around just below the air vents, and even flips it a few times.

She continues to dry it for at least 20 minutes, and seemingly not embarrassed at all, according to British news website Daily Mail.

The woman, whose identity is not known, was on board Russia's Ural Airlines from the Turkish resort city of Antalya to the Russian capital earlier this month.

Passengers on the flight were taken aback by her strange behaviour, although no one did anything further. Daily Mail quoted a witness as saying: "Everybody was looking with interest and confusion, but everybody remained silent."

Online, some people have suggested that the underwear may have belonged to the woman's child, though it is unclear if she was travelling with any children.

One social media user said: "Maybe the take-off was sort of extreme, so now she has to dry those."

Others, however, frowned at her actions.

Earlier this month, a Transavia Airlines flight from Dubai to Amsterdam was forced to make an emergency landing in Vienna after a passenger refused to stop farting.

A fight broke out between the man and other passengers mid-air, and the incident quickly went viral after a video posted online showed Austrian police boarding the plane.

Four people - two Dutch men and two Dutch-Moroccan sisters - were escorted off the flight.
