Sticking chewing gum in another person's hair is rarely condoned, however footage of a furious passenger unleashing her anger on another woman's hair has divided the internet.
Few places are people more protective of personal space than in the plane seats of an economy-class cabin. This is perhaps best illustrated by a video captured by Janelle Flom, as she watches a fellow traveller unleash her 'air rage' on the stray strands of hair of the passenger seated in front.
The strangely compelling act of vengeance has been viewed 77million since being uploaded to Facebook.
This savage confrontation is far from one sided.
Each time the woman in front replaces the strands of hair over the back of her seat, again it is flicked back by the increasingly furious passenger.
