In a case of total nervous breakdown, a passenger in the US threw computer monitors at airline staff after learning she had missed her flight. A video of her altercation with staff who tried to calm her down went viral on social media.

The incident occurred last month at Chicago’s O’Hare International Airport. The video shows the woman climbing over a baggage counter, grabbing items and yelling incessantly at Frontier Airlines employees.

After an employee pushed her back, the woman quickly grabbed a computer monitor and threw it at the employee – hitting him in the stomach. Before the employee could react, she threw a second computer monitor down.

She yells “stupid” at the Frontier employees before climbing down.

A passenger who filmed the woman’s nervous breakdown said she “freaked out” when Frontier Airlines denied her access to the plane.

According to Chicago police, the 31-year-old woman started an argument with two other women, ages 24 and 40, at the airport on July 30.

After the tantrum and attack on airline employees, she threw a cell phone at the 40-year-old woman and also punched the 24-year-old in the legs, ABC reported.

The woman then fled the airport. Police said that regional investigators are still investigating the case.
