From Hobby Sketch to Digital Earth: The Rise of Microsoft Flight Simulator

Origins

In the mid‑1970s, Bruce Artwick, an electrical‑engineering student, and Stu Momont, an MBA student, met at the University of Illinois. They shared a dorm and a passion for flying.

SubLogic and Early Flight Simulator

Bruce earned a pilot’s license and wrote a master’s thesis, “Multi‑Function Computer‑Generated Dynamic Flight Display,” which ran on a PDP‑11 and became an early flight simulator. After graduation he worked at Hughes Aircraft and continued researching 3D graphics, publishing a 3D graphics package for the Motorola 6800 in 1977.

Seeing demand for his graphics package, Bruce and Stu founded SubLogic to focus on 3D graphics software. In 1979 they released a completely assembly‑coded Flight Simulator for the Apple II, featuring simple wire‑frame graphics, a single runway, a bridge, and a mountain.

Customers asked what the 3D graphics package could do; Bruce replied, “You could make a flight simulator.” The product quickly became a bestseller on Apple computers by 1981.

Microsoft Partnership

Microsoft approached SubLogic to port the popular Flight Simulator to MS‑DOS. Bruce worked up to 16 hours a day, adding over twenty airports, weather data, coordinate systems, and radio beacons to create a more realistic experience.

In 1982 Microsoft released Microsoft Flight Simulator , which rapidly gained popularity.

Evolution of the Series

Subsequent versions (3.0, 4.0, 5.0) improved graphics, and version 5.0 introduced textures, giving objects richer detail.

In 1995 Microsoft acquired SubLogic after the Flight Simulator sold three million copies.

Porting the game to Windows required rewriting the assembly code in C, leading to performance challenges even on high‑end PCs. Windows 98 introduced 3D hardware acceleration, alleviating many issues.

Flight Simulator 2000 rendered the entire globe at 1 km resolution, impressing Bill Gates.

Modern Revival

In 2016, Microsoft’s HoloLens project inspired a new direction: using lidar and photogrammetry to capture real‑world data. Leveraging Bing Maps, machine‑learning techniques, and xCloud streaming, the revamped Flight Simulator (released in 2020) turned the world into an immersive, real‑time 3‑D environment.

The modern version includes over 37 000 airports, 15 billion buildings, 2 trillion 3‑D objects, and 3 500 TB of data, integrating live traffic, weather, and flight information.

Conclusion

From a modest line‑drawn hobby to a digital replica of the planet, Microsoft Flight Simulator has spanned four decades, turning the dream of flight into a shared, immersive reality for millions.
