Chinese-origin doctor dragged off UA flight files court papers

The 69-year-old Chinese-American passenger who was forcibly removed from an overbooked flight of United Airlines in Chicago has filed an emergency court request for the airline to preserve evidence.
David Dao, the doctor who was videotaped being dragged by police officers, has signalled that he would fight back the case in court.
Dao filed the emergency "bill of discovery" against the Chicago-based carrier in Illinois State Court demanding that evidence documenting Sunday's "re-accommodation" aboard a Kentucky-bound plane be "preserved and protected", CNBC reported.
That includes all surveillance videos, cockpit voice recordings, passenger and crew lists, incident reports and other items.

As the flight waited to depart from Chicago's O'Hare Airport to Louisville, Kentucky, officers grabbed the doctor from a window seat, pulling him across the armrest and dragging him down the aisle by his arms. He was later shown with blood on his face.
Dao "currently has no access to them and believes that serious prejudice" will befall his case if the items are not safeguarded, the court papers stated.

United Airlines chief executive Oscar Munoz has said on Twitter that the incident was "upsetting". He said they had to "re-accommodate" Dao.
Three of the officers involved in the incident have been placed on administrative leave, according to the Chicago Department of Aviation.

US President Donald Trump has said what happened to Dao was "horrible".
In an Oval Office interview with the Wall Street Journal, Trump suggested that this kind of incident could be avoided in the future if carriers remove the upper limits on vouchers they offer passengers in return for giving up their seats, the report said.
Before they began picking names, United offered passengers USD 400 and a hotel room to give up their seats, the Louisville Courier-Journal reported. When no one volunteered, the offer was increased to USD 800.
The video, posted on social media on Sunday, has been viewed by more than 120 million users in China.

It sparked outrage across Chinese social media as the airlines' decision to evict the passenger from the domestic flight was condemned as "racial discrimination".
Calls to boycott the United Airline have been rising among Chinese online users.
