The quintessential paper plane simulator, John Calhoun's shareware classic Glider first emerged in 1988 "for all Macs". Its basic premise involved the player guiding a paper plane through 15 rooms, while avoiding obstacles (including a cat) and keeping the "glider" airborne, with the help of upward air movement from vents. Subsequent versions added new rooms, features, and obstacles, but the gameplay remained essentially the same.
Glider's simple mechanics and undeniable charm spawned a dedicated fan community, consisting mostly of modders, who created new levels or "houses" for the game. There was even a fanzine for a few years in the mid-90s.
Glider PRO, the fifth major version of Glider, was released in 1994 for Macs running System 7 or better. It was repeatedly updated to run on newer hardware, and even got a commercial release on CD, before publisher Casady & Greene went out of business in 2003. John Calhoun released all versions of Glider as freeware soon after.
