The Kentucky doctor who was forcibly dragged off a United Airlines flight suffered a slew of injuries, including a concussion and the loss of two front teeth in an ordeal that sparked global outrage, his lawyer said Thursday.

Dr. David Dao, 69, suffered a “significant concussion,” a “serious broken nose,” an injury to his sinuses as well as emotional and mental injuries and is slated to undergo reconstruction surgery, attorney Thomas Demetrio said in the first official press conference since the Sunday fiasco.

“I would defy anyone to suggest that there was not unreasonable force and violence used to help Dr. Dao disembark that plane,” said Demetrio as his client prepares to sue United Airlines and the City of Chicago.

Dao was traveling Sunday with his wife, who is also a physician, back home to Louisville from a vacation in California, it was revealed.

Their connecting Kentucky-bound flight was in Chicago at O’Hare Airport when Dao was captured on video being yanked off the plane by security personnel before horrified passengers.

Dao, who emigrated from Vietnam in 1975 after the fall of Saigon, told his lawyer that “being dragged down the aisle was more horrifying and harrowing than what he had experienced in leaving Vietnam,” Demetrio said.

Dao was one of four passengers selected at random for removal from Flight 3411.

His lawyer confirmed Friday that Dao did in fact run back onto the plane after he was dragged out, but has no memory of doing so.

“The man suffered a concussion. He had absolutely zippo, nada memory of going back onto that airplane,” Demetrio said. “Not a lick of it.”

Dao, who was released from a Chicago hospital Wednesday night, has “no interest in ever seeing an airplane” again as a result of the incident, the personal injury attorney said.

Demetrio said his hope for Dao is to become the “poster child” for airline abuse of its passengers.

“Dr. [David] Dao, I believe, has come to understand that he’s the guy to stand up for passengers going forward,” he said.

Citing “the law,” he said, “If you’re going to eject a passenger, under no circumstances can it be done with unreasonable force or violence.”

“For a long time, United Airlines, in particular, have bullied us, they have treated us less than we deserve,” Demetrio said as his aired his gripes with not only the embattled airline, but also “corporate America.”

“It’s us against them. Well, we’re them, and this lawsuit hopefully will create a discussion on how we are going to be treated going forward,” he said.

Demetrio added, “Corporate America needs to understand that we all want to be treated in the same manner with the same respect, same, dignity that they would treat their own family members.”

One of Dao’s five children, Crystal Pepper, spoke out during the press conference saying, that her and her family, “were horrified and shocked and sickened to learn what happened to [Dao] and see what happened to him.”

“My dad is a wonderful father. He, along with my mother, raised five great children who have gone on to do great things,” Pepper, 33, said. “He is a loving grandfather and at the end of the day that is the person who we are trying to protect and take care of.”

Demetrio commented on the public apology United Airlines’ CEO Oscar Munoz gave Wednesday morning on ABC’s “Good Morning America,” saying it appeared “staged.”

It was the doing of the airlines public-relations team saying “you better get out there and correct what you said originally,” said Demetrio referring to an internal memo Munoz initially sent to United staff calling Dao “disruptive and belligerent.”

He also denied Munoz’s claims that Munoz and his team have tried to reach out to Dao.

“He misspoke,” Demetrio said, adding that the Dao family does “accept” Munoz’s apology, but “that’s not going to let him off the hook.”

When asked about Dao’s sordid past, Demetrio said, “Does he have serious bumps in the road? Yeah. He’s 69. I can tell u this, the law is that something that remote in time is not relevant to what occurred last Sunday.”

Meanwhile, plane incident has led to the suspension of the three police officers, who work for the Chicago Department of Aviation.
