This was the next 'biggie' after Flight Simulation and introduced a number of innovations. First, and most importantly, there are things to shoot. THey look pretty awful, and don't fly around terribly imaginatively, but they do explode very satisfyingly when shot (this can only be done with your machine gun). The other great thing about it is that your F-15 (for that's what it is) can zoom around at a fair old rate, and is much more fun to fly than the old Flight Simulation Cessna. This is partly because it's a more wazzy plane, but credit must also be given to the superior programming. There's also a bit more to look at on the ground, including a better runway and some strange square things dotted about. And the ground is green which is a great advantage. There are one or two oddities though - you can fly along for miles upside-down at an altitude of zero, which isn't too encouraging, but at least the compass is correct (Flight Simulation's had 370') and there's a nice head-up display with all the important bits on. This took over as the definitive flight sim for ages, and is still worth taking up for a spin occasionally.
Wheeeeeeeeeeeeeee! (It ain't half zappier, this one.) Wheeeeeeeeeeeeeee!
