United Airlines is in trouble. It treated a passenger badly. Security guards pulled a 69-year-old doctor from his seat. They dragged him out of the plane along the floor. Dr Dao became unconscious. His face was covered in blood. He lost two teeth and broke his nose. The doctor paid for his seat but United told him to get off the plane because a flight attendant needed his seat. Dao had to see many patients the next day. The United staff didn't listen to him.
Dr Dao is going to sue United Airlines. He was born in Vietnam and escaped from the Vietnam War. He said the United flight was "more horrifying" than being in that war. His daughter said what happened to her dad should never happen to anyone. She was shocked. A video of Dr Dao being dragged went viral on the Internet. Over 150,000 people signed an online petition for the United Airlines CEO to resign. He refused. He did not apologize at first.
