A man dragged screaming off a United Airlines flight described his ordeal as "more horrifying" than his experiences in the Vietnam War, his lawyer says.
Attorneys for Dr David Dao, who lost two front teeth and suffered a broken nose and "significant" concussion in the incident, say they will sue.
His daughter, Crystal Dao Pepper, told the news conference in Chicago they are "sickened" by his treatment.
Video of the incident has been watched millions of times online.
