amelia earhart: failure to communicate

I have become fascinated recently with the story of Amelia Earhart, who departed for her ill-fated flight from Papua New Guinea to Howland Island 75 years ago. Based on what's documented about the trip, the disappearance of plane and crew are unfortunately not especially surprising. But unsolved mysteries are often appealing to me. A group called TIGHAR (The International Group for Historic Aircraft Recovery) has departed on an expedition to Nikumaroro Island (also known as Gardner Island) to search land and sea for clues about the trip's fate. One area of criticism I heard about TIGHAR with which I agree but can't recall the source, is that TIGHAR is clinging to one possible outcome of the flight to the apparent exclusion of other plausible outcomes. Anyway, one goal of this mission is to perform underwater searches for the missing aircraft. TIGHAR has a sizable Wikipedia-style website with articles on the subject. Of potential interest to radio enthusiasts is the article, Failure to communicate.
