The full story
A flight simulator that runs in a browser tab, built by Claude Code in one overnight session from a brief by someone who grew up on a cracked copy of Flight Simulator.
It models lift and drag along each wing, simulates propellers blade by blade, and has nine real aircraft built from their real dimensions and weights, which matched published performance figures in 213 of 223 tests. Live weather brings real wind, cloud, rain and icing, and you can take off from any airport on a 3D globe.
It is 8,851 lines of code with no game engine. Claude ran five sub-agents in parallel, for research, scenery, navigation and building the aircraft from official data.
