A game by Andy Hollis published by Microprose (Makers of kick-ass flight sims) in 1985

An air traffic control simulation for the classic 8-bit platforms (Commodore 64, Atari, Apple II). If you don't have enough stress in your life, this should help.

It's 9pm, there are twelve flights circling your airport, each with 300 passengers whose lives depend on you. UA 721 has declared low fuel. Unfortunately, they're sixth in line on approach so you'll have to divert three other flights -- but wait, AA 234 is calling in an emergency . . . Gaaah!

During game design Air Traffic Controllers were consulted and the simulation reflects closely the real environment of a control tower.

A nice touch is the voice synthetizer that simulates radio chatter between the control tower and airplanes.
