A fire on an empty plane forced London's Heathrow Airport to close both its runways Friday.
Airport officials said there were no passengers aboard the Ethiopian Airlines Boeing 787 Dreamliner.
Television images showed firefighters on the scene and the aircraft apparently sprayed with fire-retardant foam.
Boeing's Dreamliner jets had been grounded earlier this year amid concerns over battery meltdowns. In April, Ethiopian Airlines became the first carrier to resume flights with the passenger planes.
Shares in Boeing fell Friday with news of the latest incident.
