Note: The following is one of a series of columns looking at the establishment of the postal system in the nation, southeast Georgia and Bulloch County. E.A. Keogh’s article, “A Brief History of the Air Mail Service” in the “Saga of the U.S. Air Mail Service” (1962), reported that the first recorded aerial mail transportation occurred in 1870. It was an apparently unmanned balloon flight made on Sept. 23, 1870, which carried 500 pounds of mail.
