A medium shot of an aerospace engineer in a 1950s office, illuminated by the warm, focused glow of a green banker's lamp. The engineer is intently studying the open pages of NACA Technical Note 4047, which features technical diagrams of blunt-body reentry shapes. Beside the document lies a brass drafting compass, a pencil, and a hand-drawn sketch of a detached shockwave pattern on aged, yellowed drafting paper. The atmosphere is quiet and studious, with a texture of worn mahogany, ink-stained paper, and cold steel instruments. High-resolution historical realism, controlled chiaroscuro lighting, cinematic 16:9, muted olive and tobacco brown palette, archival scholarly aesthetic.
