You approach Paine Field and the scale hits you before you see a plane: a hulking hangar door yawns open, metal skin glinting under a low Northwest sun, and the air carries a faint tang of oil and heated aluminum. From the Strato Deck the factory floor becomes an ant farm of scale and purpose — 747s, 777s and 787 Dreamliners reclining in various stages of assembly while riveters, robots and riggers move through choreographed tasks.
