A Spirit Airlines Airbus A319-100, registration N519NK performing flight NK-708 from Chicago O’Hare,IL to Boston,MA (USA), reached the top of descent into Boston when a strong odour of dirty socks occurred, both flight crew became aware of the odour. When ATC called to hand them off to the next frequency, both flight crew were unable to interprete the frequency and unable to select the new frequency until they finally managed to write it down after several repeats by air traffic control and process it from there. Operating increasingly erratically the first officer finally donned his oxygen mask, recovered a bit and recognized that the captain had sunk into his seat and was incapacitated. The first officer put the oxygen mask on the captain, too, who subsequently began to recover as well. The flight crew managed to land the aircraft without further incident, however, did not recall how they managed to land or taxi the aircraft.
Both flight crew continued two more sectors the next day after a night’s rest at a hotel, then both pilots went to see doctors. The captain was diagnosed with internal bleeding and abnormal blood values consistent with ToCP poisoning. Both flight crew were sick with diarrhea, vomiting, tremors, body shakes and feeling of tiredness that began to subside only after a couple of days.Source Aviation Herald – read full report and few video HERE
