Three pieces of a pocket knife and fragments of what might be a broken cosmetic glass jar are adding new evidence that Earhart and her navigator Fred Noonan landed and eventually died as castaways on Nikumaroro, an uninhabited tropical island in the southwestern Pacific republic of Kiribati. The island was some 300 miles southeast of their target destination, Howland Island.

“These objects have the potential to yield DNA, specifically what is known as ‘touch DNA’,'” Ric Gillespie, executive director of The International Group for Historic Aircraft Recovery (TIGHAR), told Discovery News in an email interview from Nikumaroro.
