Guest asked Putnam to find a suitable candidate, and he eventually came up with the then-unknown aviatrix, Amelia Earhart. As it turned out, they shared many common interests: hiking, swimming, camping, riding, tennis and golf. When Putnam first met Earhart he was still married to Binney. After she completed her flight across the Atlantic, Putnam offered to help Earhart write a book about it, following the formula he had established with Lindbergh in the writing of ""WE"". The resulting Earhart book was "20 Hrs., 40 Min." (1928).
