Dr. Nicholas Kohanowski was a geologist and mining engineer, University of North Dakota. He was probably enjoying a relatively peaceful academic life when, in 1959, four cases of "slag falls" from his home state of North Dakota came across his desk. These falls had occurred in 1940, 1953, 1957 and 1959. Kohanowski, as a professional geologist, felt that he could rather easily "understand" these events and place them in the conventional world of common reality. He couldn't. Actually, Kohanowski got entangled in this business of strange falls in 1957 due to the Langdon, ND fall, and then the 1959 one was brought to his attention in turn. He was on the original NICAP Panel of Special Advisers. (Ridge)
