This was an Air Traffic Control simulation game, originally released in 1986 for the C64, Atari 800XL, and the Amiga. It was never ported to either MS-DOS nor Windows. Until now.

The author wrote this for XP from scratch. Although the original game had simple graphics, it was a programming milestone at the time, as 8-bit machines mimicked a human voice (100% tonal accuracy) and radio static, and the Atari version utilized 16-bit sound programming.

You start off as a GS trainee at one of the various airports around the nation. You can experience obstacles such as mountains, thunderstorms, aircraft conflicts, and even crashes. You handle takeoffs, landings, and fly-throughs. Your altitude block is from 0-5,000 feet. The XP version has game save and replay capability.
