About this game

Take off from any airport in the world, picked by its ICAO code, and fly over real elevation, satellite imagery, water and buildings. There are 9 real planes built from their real dimensions and weight, a full cockpit with instruments that drift like real ones, coupled ILS approaches at night, and live weather: real wind, cloud, rain on the glass and ice building up on the wings. Ten different things can break mid-flight.

Lionel Mora says Claude Fable 5.2 built it overnight in 8,851 lines of code, with no game engine. Lift is calculated for each part of the wing and the propellers are simulated blade by blade; flown through a test pilot's checks, the planes matched their real performance figures in 213 of 223 tests. The project is open source.
