Last Sunday  the video, which surfaced Monday, showed a passenger removed from United flight 3411 at Chicago O’Hare International Airport.


Several passengers recorded the incident on their phones and posted video on social media showing three Chicago Department of Aviation security officers dragging the man, who has not been identified, down the aisle by the arms and legs while other passengers shout in protest.

He continued to resist after he was removed and ran back onto the airplane, face bloodied from the encounter.

United Continental Holdings (UAL)’ stock was off about 4%, knocking off close to $1 billion off the company’s market value. By late afternoon, after a mea culpa from the CEO, the stock had recovered from the worst losses — but its market value was still off by $250 million.
