Kennedy Approach is (or was) an ATC simulation game that first appeared
on the C64 back in the eighties. It was the first game to use a speech
engine (computer generated voice) which was quite an achievement for a
64kb game. It was probably the first ever realtime strategy game (RTS).
It now runs on Windows 98 and higher. It also works in Linux using
wine. Kennedy Approach is a freeware game and also fully ****table since
it does not disturb the Windows registry in any way.
If you are currently using Kennedy Approach you can update from within
the game itsself or if not, then you can find a download (1.4 Mb) link
at the author's home page,

where among other good things you will find the online manual and a
forum dedicated to the game.
Enjoy!
