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.
