An expedition to find out what happened to pioneering US aviator Amelia Earhart is returning to Hawaii without finding the evidence it was looking for.
The International Group for Historic Aircraft Recovery (Tighar) believes that Earhart and her navigator crashed on a Pacific island and died soon after.
A team was searching for evidence of the 1937 wreckage in the waters around Nikumaroro, but failed to find anything.
Earhart was the first woman to fly solo across the Atlantic Ocean in 1932.
She took off from Newfoundland in Canada and was heading for Paris in France, but landed well off-course in a field near Londonderry.
Yesterday marked the 115th anniversary of her birthday.
