A Delta Airlines Boeing 767-400, registration N845MH performing flight DL-1 from New York JFK,NY (USA) to London Heathrow,EN (UK) with 225 people on board, was enroute at FL340 about 210nm northeast of Gander,NL (Canada) when the crew observed an "IAS DISAGREE" indication, declared emergency and decided to return to New York. The aircraft landed safely back in New York about 4 hours later.

The Canadian TSB reported: "When in cruise flight at about 50°57' N, 050°11' W, the flight crew observed an indicated airspeed disagree message. The flight crew referenced the quick reference handbook, identified the malfunctioning air data computer and contacted company operations and maintenance departments. The flight crew decided to return to KJFK, then declared an emergency and coordinated with the ATS for the air turnback to KJFK where a landing was made without further incident. Maintenance replaced the first officer side air data module, conducted a pitot static system test, and the aircraft was returned to service."
