United Airlines CEO apologises after passenger dragged off overbooked flight

The CEO of United Airlines has apologised what he said is the truly horrific removal of a passenger from an overbooked flight.

Oscar Munoz said he continues to be disturbed by the incident, during which a passenger was forcibly dragged, screaming, off a plane.

He said the company would fix what's broken so it never happens again.

United's parent company's share price plummeted after a video of the incident went viral on Twitter.

The footage taken inside the airliner shows a man being pulled out of his seat and dragged, screaming, down the aisle.

He is later seen with blood on his face.
