New York : A flight from Newark to Denver was diverted to Chicago after a mid-air brawl erupted when a man set up a gadget that would not let the woman in front of him recline in her seat and she tossed a cup of water in his face. The scuffle forced the plane to be landed in Chicago, where the warring passengers were both evicted. The mid-air fight started because the man, seated in a middle seat, used a “Knee Defender” gadget that attaches to a passenger’s tray table and stops the person in front of them from reclining. A flight attendant asked the man to remove the device — which are banned on the Airline’s flights but he stubbornly refused. The female sitting in front of him then stood up, whirled around and tossed a cup of water at her tormentor, authorities were quoted as saying by the New York Post. That is when United decided to make the unscheduled stop at Chicago’s O’Hare Airport, where the flight was met by Chicago cops and Transportation Security Administration officials, reports PTI.
