A United Airlines flight from New Jersey to Brazil ended up circling over the Atlantic Ocean for nearly two hours Wednesday and making an emergency landing because of a mechanical issue, flight officials said. Flight 149 departed from Newark Liberty International Airport at 11 p.m. ET Wednesday night, bound for São Paulo–Guarulhos International Airport with 256 passengers on board, according to the flight's history. The plane experienced a “mechanical issue shortly after takeoff,” United Airlines said in a statement, revealing that initial maintenance inspection points to a hydraulic pump issue. The plane, a Boeing 777-200, landed after the crew reported an "emergency," the Federal Aviation Administration said, noting that an investigation was underway.
