滑走路離陸、HUD、追従カメラ付きのブラウザ向けフライトシミュレーター

Build a browser-based 3D flight simulator. Start with a title screen and a Start Flight button, then place a passenger airliner at the end of a long runway in a bright green countryside under a blue sky. The player controls throttle, pitch, roll and yaw with the keyboard, accelerates down the runway, rotates and takes off, then flies freely. Include a HUD showing speed, altitude, heading and throttle, plus a chase camera that follows the aircraft. Add simple terrain, runway markings and a few buildings for scale. Flight physics should feel smooth, with no stutter or jitter at normal frame rates. Deliver one project that runs in the browser, and finish when takeoff, climbing, banking and landing all work reliably.
