25 Sep 2026, Unit2 service-branch sweep: the stored Secondary Unit "Army" was CLEARED. It was not a sub-unit, it was a service-branch word, and it CONTRADICTED this record's own Branch, "Air Force". Across the roll 787 records carried such a contradiction; judged against Corps and Regiment -- independent of both columns -- the evidence backed Branch 744 times and Unit2 not once. Branch is therefore kept and the contradicting word removed. Nothing is guessed: this man's branch of service is already recorded, and his sub-unit, if any, is simply not known.
5 Oct 2026: IMPOSSIBLE UNIT, NOT CHANGED: stored Regiment "South African Air Force" and this stored Unit "South West Africa Police Counter-Insurgency Wing: Ops-K Division (KOEVOET)" cannot both be right for a 1938 Air Cadet -- Koevoet was formed decades later. Col (rt) Graham du Toit Last Post, 5 Oct 2026, and Bushwar Books both name the "South African Corps of Officers" at Zwartkop Air Station. AGE CONFLICT: stored Age 18; source gives 19. RANK: stored "Cadet"; source says "Air cadet". Flagged for review; the Unit field looks like contamination from a later Koevoet record but is not cleared here without a human decision. Crash details (Avro 621 Tutor #728, collision with Tiger Moth ZS-AKS near Voortrekkerhoogte) match exactly.
5 Oct 2026: UNIT CORRECTED. Stored Unit "South West Africa Police Counter-Insurgency Wing: Ops-K Division (KOEVOET)" was chronologically impossible for a 1938 air cadet (Koevoet formed decades later) and looks like contamination from a later record. Replaced with "Zwartkop Air Station", per Col (rt) Graham du Toit Last Post, 5 Oct 2026 ("based at Zwartkop Air Station in Pretoria") and Bushwar Books (same). AGE CORRECTED: 18 -> 19, per both sources. RANK: "Cadet" -> "Air Cadet", per both sources. REGIMENT NOT CHANGED: stored "South African Air Force"; both sources name "South African Corps of Officers" -- flagged for review.
