  Why it's still open: Obtain Western Defense Command records Bounded search: the official history 'The Army Air Forces in World War II' vol. I pp. 283-284 (notes 80-86) documents Knox's 'false alarm' statement and the Army's conflicting account, but it is a secondary history. Marshall's 26 Feb 1942 memo to Roosevelt was not found as a scan. (chunk F, 2026-11-12)
