A Delta Airlines Boeing 767-400, registration N833MH performing flight DL-4 from London Heathrow,EN (UK) to New York JFK,NY (USA), was enroute at FL320 about 290nm westnorthwest of Dublin (Ireland) about to enter Oceanic Airspace when the crew reported there had been a loud bang at the left hand side of the aircraft followed by the smell of smoke in the cockpit. The crew turned around and diverted to Dublin for a safe landing on runway 28L about 70 minutes after turning around.

The aircraft remained on the ground in Dublin for about 4.5 hours, then continued the journey and reached New York with a delay of about 7 hours.
