Condensed/recycled version of the @Gaurab 2026-04-29 turbine-blade primary (cited above). Same numbers ($600K/set, 90 weeks, 3 companies on Earth), but Gaurab's substantive content is dropped — the China $42B reverse-engineering case, the 500°C-above-melting-point + 20,000 RPM + 10,000g operating envelope, the closing metallurgy-moat quote, the 60-year framing. What @Ren_aramb adds: the ticker tags $HWM (blades), $ATI (alloy), $GEV (assembler), plus the closer "Interesting play."
