It's a great, very realistic, sim. It has an excellent mission creation program. Its graphics are very good for its era. I have it on my old PII, 450 mhz, w/Win98SE, VooDoo 2 graphics and on my PIV, 3.6 ghz, w/WinXP, nVidia6600 256 mb, and Zeckenseck's glide wrapper. It is more stable on the older system.
Landing the "wallowing cow" is easier than you might think, but you cannot plop it down on the runway. I had trouble landing it at first, but it is easy now.
Try this. At about five miles out keep your speed to about 200 miles per hour. Use a a low angle approach to touchdown: That is, keep the flight path very flat as you near the end of the runway. Stay at around 200 mph as long as you can, and begin to decrease speed gradually about one mile out. Just before touchdown you cannot make large adjustments like pushing the nose down or pulling it up sharply. Note: Be sure to set up you HUD to show the throttle percentage that is applied. This really helps flight control.
Have fun.
