Two US balloonists who went missing over the Adriatic Sea while taking part in an endurance race are unlikely to have survived, race organisers have said.
Richard Abruzzo and Carol Rymer-Davis disappeared in a thunderstorm on Wednesday off the east coast of Italy.
Radar readings from their balloon's tracking device showed they plunged towards the sea at 80km/h (50mph) before signals stopped.
The pair were taking part in the Gordon Bennett gas balloon endurance race.
Ships and aircraft from Croatia, Italy and the US continued searching for them on Friday.
