A Boeing 787 Dreamliner operated by the Polish airline LOT made an emergency landing Friday at Scotland's Glasgow Airport, ABC News reported.
No injuries were reported, it added.
Airport spokesman Brian McClean said that the flight from Chicago en route to Warsaw with 248 people on board landed safely. He said the landing was made at the request of the captain.
LOT spokeswoman Barbara Pijanowska-Kuras said the emergency landing was required according to safety procedure after the crew received a warning from the firefighting system in the luggage compartment.
The airport declared a full emergency as a precautionary measure. However, officials said there was no fire or smoke reported, making it possible to have the aircraft taxi to the main terminal building.
The airport remains open as normal. Pijanowska-Kuras said all passengers remain on board the aircraft as technicians check for a problem.
