The first reference to the Bombers in the Ithacan was an article on October 27, 1939. And the first reference to the Bombers in the Ithaca Journal was not until December 1944. Prior to that, he worked for the Syracuse Journal . Clearly Jansen was active in the media as a reporter about events at Ithaca College. However, the lack of references to the Bombers in the Ithaca Journal does not support the hypothesis that Jansen single-handedly generated and forced the adoption of the name.
Nobody really knows.
