Airfight is an early 3D graphics-based multi-user flight simulator, created on the University of Illinois Urbana-Champaign (UIUC) Control Data Corporation (CDC) PLATO system in the early 1970s.[1][2][3]
The software was the first ever 3D flight simulator and the first multi-player flight simulator.[2] The first version was developed by Brand Fortner with Kevin Gorey in the summer of 1974.[4] After its release, it became the most popular game on PLATO until Empire became more popular. This software probably inspired the UIUC student Bruce Artwick to start the company Sublogic,[4] which was acquired and later became Microsoft Flight Simulator.[5]
