A fresh expedition to find out what happened to celebrated US woman pilot Amelia Earhart is beginning - 75 years to the day since she took off on her last flight.

Researchers will dive around the uninhabited Pacific island of Nikumaroro looking for clues.

Ric Gillespie, who is leading the expedition, explains to the BBC's World Today how the search will be carried out and why he thinks Ms Earhart and her navigator Fred Noonan crashed there.
