Far from a combat photograph, this item is a pilot's weapons delivery data card — a quick-reference table of dive angles, release altitudes, and airspeeds for dropping the MK-82HD high-drag bomb. Dated 15 July 1971 and preserved among a Da Nang F-4 Phantom collection, cards like this were essential tools for Vietnam War-era fighter-bomber crews, translating complex ballistics into simple, actionable numbers before every strike.
