I'm looking for a WW2 flight-sim game that I think was called "P51: Mustang", although I'm not completely sure that's the actual title.

Brief Description:
As you can guess from the name, this game involved flying a P51 fighter in various missions WW2's European theatre. It was first-person flight-sim, with extremely simple graphics (ground = green, sky = blue). Hardly sophisticated, but infinitely playable. Release date is probably before '94 or '95.

I've already done as much digging for it as I can myself, so if anyone's run across it, I'd be greatful to be pointed in the right direction.
