The Air Mail Mystery survives as a short run of 1932 syndicated chapters preserved by the Old Time Radio Researchers. The episodes follow a mail pilot through crashes, accusations and sabotage on the transcontinental route — the same air-mail service whose fatal accident rate had made national news two years earlier. Exact transmission dates were never recorded on the discs, so only the year is known for the surviving chapters. Public domain; streaming from the Internet Archive.
