A-10 Cuba! was the long awaited sequel to the original A-10 Attack! flight simulator. A-10 Cuba! had the same impressive flight model as its predecessor, except the graphics had become significantly more detailed and thus required a computer with a bit more power. Graphical and other improvements included tire smoke when landing or skidding, runway taxi-way lighting, the Air Combat Command insignia on most U.S. aircraft, increased number of polygons (making objects appear much more round than they appeared in A-10 Attack!), and weapon damage was significantly upgraded (increased realism) and ground vehicle physics were more realistic.

The interactive cockpit doesn't seem to work right under SheepShaver, but everything else looks good. There might be a way to get it working yet.
