Maybe so, says an article on Discovery News. Latest theory - she and her navigator perished as castaways on the remote South Pacific island of Nikumaroro after an emergency crash landing. Possibly having been eaten by giant coconut crabs which are the scariest bugs on the planet
(OK, probably not technically a "bug" but still the largest land animals with exoskeletons up to 3 feet, capable of cracking coconut shells with their giant pincers. Or you know, human bones).
One hopes they were dead before the crabs got to them.
