A passenger plane was forced to make an emergency landing after the pilot reported smelling smoke in the cockpit.
The American Airlines flight, from London Heathrow to JFK in New York, touched down safely at Dublin airport in Ireland at about 1000 BST.
All 135 passengers got off the Boeing 777-200 to allow it to undergo an inspection by engineers while airport fire services were on standby.
It is thought there may have been a problem with an oven in the galley.
The plane was expected to resume its journey at midday.
