Hard to Find Hayden C. Hewes Work: Piedmont, Missouri 1973

The small self-published work called EARTHPROBE, by Oklahoma based investigator Hayden C. Hewes, chronicled the strange events at Piedmont, Missouri in February of 1973.  Dozens of citizens, including police officers, reported strange sightings, odd happenings and more. Events related to the incident may have been noted as far away as southern Illinois.  Read an article from a North Carolina newspaper here: UFOs Found In TV Broadcasts (realtvufos.blogspot.com).

Photographs were taken but it is unclear what became of them, there is a connection to nearby Clear Lake and a possible sighting of an object leaving the waters of the lake. 

Hewes, as lead investigator and founder of the International UFO Bureau based in Oklahoma City at the time, went to Missouri to do on-site research. In this window of time it is known he traveled to Kansas, Texas and Missouri doing research with teams related to UFO's and other mysterious events. 

Today his books are mostly found in research libraries, private collections, and an occasional archive.
