premise: Last Flight is a book published in 1937 consisting of diary entries and other notes compiled by aviation pioneer Amelia Earhart during her failed attempt that year at flying solo across the Pacific Ocean. Her husband, publisher George Palmer Putnam, edited the collection which was published posthumously as a tribute to his wife.
hypothesis: Amelia Earhart's husband was on the plane with her when it crashed.
reason: Since he survived and was able to publish the book, he definitely wasn't on the plane that crashed.
