It's the coldest of cold cases, and yet it keeps warming to life. Seventy years after Amelia Earhart disappeared, clues are still turning up. Long-dismissed notes taken of a shortwave distress call beginning, "This is Amelia Earhart...," are getting another look.

The previously unknown diary of an Associated Press reporter reveals a new perspective.

A team that has already found aircraft parts and pieces of a woman's shoe on a remote South Pacific atoll hopes to return there this year to search for more evidence, maybe even DNA.

If what's known now had been conveyed to searchers then, might Earhart and her navigator have been found alive? It's one of a thousand questions that keep the case from being declared dead, as Earhart herself was a year and a half after she vanished.
