Family and attorneys of doctor dragged off United Flight 3411 speak

A Kentucky doctor who was dragged from an overcrowded United Airlines plane remained hospitalized Tuesday in Chicago where he was "undergoing treatment for his injuries," according to a family statement.

The Louisville, Kentucky-bound flight attracted international attention earlier this week when crew members called law enforcement to remove a ticketed passenger from the aircraft to make room for United employees.

Jarring video emerged on social media the next day showing officers forcibly removing Dr. David Dao, 69 from the plane, leaving him bloodied as nearby passengers looked on in horror.

Dao's attorney and daughter held a press conference Thursday saying that Dao had suffered a 'significant concussion' in the altercation. He was released from the hospital Wednesday night, but remains shaken

As of Wednesday, the Chicago Department of Aviation has suspended three officers in connection with the incident pending the outcome of an investigation.

In an exclusive interview on 'Good Morning America,' United CEO Oscar Muñoz issued a public apology and pledged to make the situation right.

"That is not who our family at United is. And you saw us at a bad moment. And this can never, will never, happen again on a United Airlines flight," Muñoz pledged.
