As the video begins, the angry female passenger can be heard screaming in the plane's aisle. "Where is it?" she is heard saying.

"Ma'am, we are landing," a flight attendant is heard telling the woman. That's when the situation turns violent. "Sarah, step back," the flight attendant is heard saying.

But the angry woman is seen walking towards the flight attendant who shouts with more urgency in her voice.

Other crew members also step in in order to help their colleague, the video shows just before ending.

According to the Chicago police, they were called for "a disturbance" that happened on Flight 476 and responded to its gate at around 6am, according to New York Post.

"A disruptive customer on a flight from San Francisco to Chicago was removed by law enforcement upon landing on Sunday, and one member of the flight attendant crew was taken to a hospital for evaluation," United Airlines said in a statement.

Three people, including one of the flight attendants, were taken to nearby Resurrection Hospital for observation, the police said.

No serious injuries were reported in the clash, according to United Airlines. The Federal Bureau of Investigation (FBI) has also launched a probe.
