The one file-era case worked at file level: South Bend, 13 October 1948

Project Blue Book Unknowns catalogue, entry 120 · the county's case, not imported beyond its file

The county's one file-era case is worked here at the strength its surviving file summary allows — and no further, because the file allows no further. The case stands in Brad Sparks' Comprehensive Catalog of Project Blue Book UFO Unknowns, compiled from the Fund for UFO Research and National Archives indexes, as entry 120 of its 1948 run: 13 October 1948, South Bend, Indiana (41.68° N, 86.26° W); witnesses Brooke and Thompson; the catalogue's tentative evaluation prints with a question mark — "Debris?" — and its sources are the McDonald list and the Saunders/FUFOR Index. Inclusion in that catalogue means the Air Force's file left the case among its unknowns: it is an official Unknown, one of the 701 class, not a newspaper tale. Beyond that entry, the surviving secondary record is unusually bare — a modern archive of the case summarises it in one line: no further detail preserved in the surviving source material. The checklist's floor form — a works case, a disc over the Studebaker works — is how the South Bend build frames this date; this section prints the catalogue record as the file-level fact and does not import a narrative the file summary does not contain: no disc, no factory, no chase is asserted here, because none stands in the record this section read. The settler for any deeper working is named in the audit's terms and is current: the Project Blue Book case file itself, National Archives, from which the catalogue entry derives. What this article settles is the case's existence, date, place, witnesses, official posture and tentative evaluation — file-level at catalogue strength, with its thinness printed as part of the finding. Lakeville's share is unchanged: the case is the county seat's, thirteen miles north, and no Lakeville case exists in the same catalogue.
