Released for the Apple II computer as A2-FS1 Flight Simulator with British Ace - 3D Aerial Battle,[3] it was their first product after forming Sublogic,[4] has black and white wireframe graphics, with very limited scenery consisting of 36 tiles (in a 6 by 6 pattern, which roughly equals a few hundred square kilometers), and provides a very basic simulation of one aircraft.
