SN CORRECTION 25 Aug 2026 (year-prefix method): ServiceNo 81228116BG cleared -- per the documented SA force-number convention (data/SA_SERVICE_NUMBER_NOTES.md), the prefix '81' implies registration circa 1981 (usually age 16), i.e. birth circa 1965. This record's own Age/DateDeath implies birth circa 1919, a mismatch; PersonNumber 30618 (Hanekom, implied birth circa 1965) fits instead. Original value: "81228116BG". | Unit was contaminated with an unrelated Army unit (Infantry Battalion/Artillery Regiment/Commando/Special Service Battalion) that makes no sense for Air Force personnel -- found 28 Aug 2026 while investigating a similar report (PersonNumber 30827, Janse Van Rensburg). Affects 32 "ref. 85 years of SAAF" records in total, all correctly Corps = South African Air Force but each with a different, unrelated ground-forces Unit value -- looks like a batch-import misalignment bug, not a single bad value repeated. Cleared rather than guessed at a correct Unit.
