January 1957 · index test · Run B #171
Tested negative at index strength: the register's floor opens the next index year after the flap years, and this section opened it: the Blue Book unknowns literature and the NICAP chronologies for 1957 were searched for a South Bend, Mishawaka, Osceola or Penn Township entry in January 1957. None surfaced — no Unknown of that month and place stands in Berliner's compilation, and no county case of January 1957 is carried in the chronologies searched. The year's great national flap belongs to November 1957, not to this county's January. Named gap: the case-file series itself, NARA microfilm T-1206 as browsed on Fold3, is the settling instrument for a January 1957 county report filed under a neighbouring place-name; the open indexes are searched whole and are empty.
Searches shown in the article: Berliner's Blue Book unknowns compilation and the NICAP chronologies, read for January 1957 Indiana entries; the Air Force year table (1957: 1,006 reports, 14 unidentified) from the DoD UFO packet.
