Article: "Mariana UFO Incident: Great Falls’ Visiting Voyagers"

The History Museum & Research Center, Great Falls, Montana

My comment:

On 15 August 1950, Nicholas Mariana filmed two UFOs.

The article includes eight 1950 newspaper articles and a segment from the 1956 film, Unidentified Flying Objects: The True Story of Flying Saucers.
