Rank 57 documents Apollo 1 — designation AS-204, the Apollo Command Module checkout that ended in tragedy on Launch Complex 34 on 27 January 1967. Virgil 'Gus' Grissom, Edward H. White II, and Roger B. Chaffee were conducting a plugs-out integrated test of the Block I Command Module when a fire erupted in the pure-oxygen cabin at greater than one atmosphere pressure. The crew perished within seconds; the Block I hatch design that opened inward and required multiple steps to operate became a focal point of the investigation board chaired by Floyd Thompson. NASA paused crewed Apollo flights for twenty months while Block II redesigns introduced mixed-gas prelaunch procedures, outward-opening hatches, fire-resistant materials, and rewired plumbing. The mission never flew; its legacy is every Apollo crewed flight from Apollo 7 onward. Wallimilist renders the Block I CM technical drawing, crew mission patch tribute, Earth horizon, and foil APOLLO 1 title in restrained archive dignity exactly as the master PNG dictates — 1967 memorial palette, NEVER FLEW kicker, and curator copy on safety redesign heritage.
