Fighter Bomber (known as Strike Aces in the US) is a combat flight simulator developed by Vektor Grafix. It was published by Activision in 1989 for MS-DOS, Commodore 64, and Atari ST, and one year later ported to Amiga, ZX Spectrum, and Amstrad CPC.
The game wasn't famous for its fast framerate - it was a bit slow, especially on standard Amigas - but several people liked it for its atmosphere, excellent graphics, and relatively easy controls. This is not Falcon or F29 Retaliator, but it's still a title that made the history of flight sims.
