As a pilot who’s had a chance to fly in an f-35b for real, it's a damn impressive airplane. The only downside in my couple of flights was, as the correspondent mentioned, the relatively inadequate pitch authority of the aircraft and the relatively short range. The avaionics are amazing and the controls are super easy to use. The aircraft automatically stabilises itself and handles stuff like trim for the pilot. All around, a fun plane, despite the price being twice the original quote per airframe and many times more for the development costs.
