Flight Unlimited is a 1995 aerobatic flight simulator video game developed and published by Looking Glass Technologies. It allows players to pilot reproductions of real-world aircraft and to perform aerobatic maneuvers. They may fly freely, race through floating rings against a timer or take lessons from a virtual flight instructor. The instructor teaches basic and advanced techniques, ranging from rudder turns to maneuvers such as the tailslide, Lomcevak and Immelmann turn.
Flight Unlimited was the first self-published game released by Looking Glass Technologies. It was intended to establish the company as a video game publisher and to compete with flight simulator franchises such as Microsoft Flight Simulator. Project leader Seamus Blackley, a particle physicist and amateur pilot, conceived the game in 1992. He felt that other flight simulators failed to convey the experience of real flight, and reacted by coding a simulated atmosphere for Flight Unlimited that generates aerodynamics in real-time. Aerobatic pilot Michael Goulian endorsed the game and assisted the team in making it more true to life.
Flight Unlimited received positive reviews from critics and was a commercial success; its sales exceeded 780,000 copies by 2002. Reviewers lauded its realism, flight instruction, graphics and sense of flight, but some criticized its high system requirements. The game was followed by two sequels: Flight Unlimited II (1997) and Flight Unlimited III (1999). The combat-oriented Flight Combat was planned as a direct follow-up to Flight Unlimited, but a string of development issues resulted in its belated 2002 release as Jane's Attack Squadron.
