- Detailed flight dynamics: aero lift/drag/side-force with smooth stall, control-surface moments, stability derivatives, engine spool with prop torque and gyro precession, inertial coupling, ISA atmosphere, ground effect, 3-point gear handling, landing vs crash classification. - Pure ESM, zero build step; three.js vendored locally. Deterministic simulation; physics core is Node-testable (14 node:test cases). - Procedural 8 km world with runway, water, sky dome, cloud wrap; DOM instrument panel (attitude indicator, tapes, VSI, lamps, stall warning). - Controls: WASD/arrows, Q/E rudder, Shift/Ctrl throttle, F flaps, G gear, B brakes, C camera (chase/cockpit/orbit), R reset, P pause, D debug.
