The whole install is 256 MB and has most of the features CFS3 brags about now. The virtual cockpit alone is worth the price of admission and IMHO even outclasses CFS3. I chose the Spitfire for this tour, but the rest of the planes are similar in detail.
This is the opening screen.

A trip to the museum side shows the available planes. This is a montage of 3 different shots, the real thing is much more impressive

Available planes are in order.. Spitfire, BF-109, P-38 Lightning, Me 262, P-47, P-51, FW-190
Clicking on a plane will give you several surprises including views of the weapons, engine, and cockpit.

and the option of bringing up this screen which gives you a video about the plane, test flying the plane, and the story of it's development and variations.

Flying is a dream. The pic speaks for itself.

The virtual cockpit is almost photoreal and no where near as hard on the framerates as CFS3

The mission builder allows for up to 32 ac in a furball with 4 different experience levels and everything from an ai C-47 to a Ar-234. It also takes only seconds to use.

There are many more surprises in this game, but I'll let you find them for yourself...
