Cancelled Amiga versionThe planned Amiga version was never completed, although Birds of Prey (also from Electronic Arts) did many of the same things on that system the same year.
OEM versionA special edition was bundled with the Gravis UltraSound in 1993. This version featured a whole new soundtrack intended to show off the capabilities of this sound card. The music used custom samples instead of the standard MIDI instrument set.
SpeechThe starts with a digitized message from Chuck saying "Welcome to Chuck Yeager's Air Combat". There are other digitized lines by him such as: "Remember, it's the man - not the machine" which are played after a mission and give feedback about the completion and success rate.
But hidden in the game are some other digitized snippets from the actual game designers, such as:
"Welcome to Brent Iverson's Air Combat"
"Welcome to Paul Grace's Air Combat"
"Welcome to Cynthia Hamilton's Air Combat"
"Oh my." (Spoken by Chuck Yeager)
These snippets were found by decompressing the sound library and picking at it. It is unknown if here is a legitimate way to get the sounds to play, however, such as starting up the game on someone's birthday, or a holiday.
