WorldFlightSim – Free flight SIM in browser with Google Maps
Google Maps 3D flight sim, but it's a thin interactive wrapper without depth or persistence.

Real-world geography in a browser—technically impressive, but lacks the depth or physics of MSFS or X-Plane.
Flight sim enthusiasts, casual pilots, geography explorers

Google Maps 3D flight sim, but it's a thin interactive wrapper without depth or persistence.
IFR procedure training in a browser when X-Plane costs $300 and requires downloads.
The post ties classic MacCready speed-to-fly theory to an RL framing and carefully walks through sink-vs-speed modeling instead of handwaving the physics. It's a thoughtful niche read, but the landing page is just an article — no simulator, no training curves, no agent demo or downloadable artifacts — so it's hard to judge any technical execution beyond the math.
Proof-of-concept flight sim for the author's own Spectre language.
Packaging photorealistic city flyovers into one downloadable HTML demo is the project's killer move — instant launch, no account, and a surprisingly complete HUD with instrument readouts and selectable aircraft. It's clearly engineered for spectacle (fast streaming tiles/shaders and in-browser audio) and works as a demo of what's possible on the web; what it doesn't yet sell as are deep flight physics, multiplayer, or long-form persistence, so treat it as a technical showpiece with real play value.
