Campbell did indeed reject "Stowaway", based on the story's "general air of amateurishness, constraint, forcing". On 3 August Asimov submitted the story to "Thrilling Wonder Stories". When "Thrilling Wonder" rejected it, Asimov mailed the story to the offices of "Amazing Stories" in Chicago, which also rejected it. In the summer of 1939, following the sale of some later stories, Asimov revised "Stowaway", retitled it "Magnetic Death", and again submitted it to "Thrilling Wonder Stories" and "Amazing Stories", and again it was rejected. Later that year, Asimov's friend Frederik Pohl became editor of two new magazines, "Astonishing Stories" and "Super Science Stories". He accepted "Magnetic Death" on November 16, 1939, and it finally appeared in the April 1940 issue of "Astonishing Stories" under the title "The Callistan Menace". Asimov once described Pohl as "an inveterate title-changer".
