In Hong Kong, investigators examine Cathay Pacific flight 7802's engine issues. They retrieve the black box to analyze flight data, revealing that the thrust levers moved but fuel flow remained constant, indicating a metering valve malfunction. The valve, sent to Rolls-Royce for analysis, was found coated with a super absorbent polymer used in refueling trucks to prevent water contamination. This polymer, when in contact with water, forms a gel, which should remain in the filter but somehow ended up in the aircraft's fuel system.
