Special Report 14 is the Air Force’s large statistical pass at the early saucer files, contracted to Battelle. It sorted thousands of reports by reliability and by how ordinary the explanation was. The headline at the time was that most cases were identified. The quieter finding, still in the tables, is that the better-documented reports were more likely to stay unidentified, not less.

The Air Force used the report to say the problem was shrinking. Independent readers used the same tables to say the opposite. The paper is public. The argument is in the percentages, not in a hidden annex.
