Some years ago, I went for a glider maiden flight (in real life, I mean). It was a 20 minutes flight above a very nice area in southern France. Before the flight, the instructor pilot asked me if I ever piloted a plane before. When I told him that I never piloted a real plane, but that I had several hundreds of hours in simulators, including for gliders, he laughed at me, telling that simulators are ridiculous and have nothing in common with real life, making fun of me, kind of...
Then we took off (towed by a plane), and during flight he proposed me to take controls... and I just flew the glider alonside the hill (ridge lift due to wind), going back and forth, gaining altitude, doing U turns etc... The glider was performing/reacting EXACTELY like the default FS9 glider
Needless to say, the instructor was not laughing at me anymore...
The very cool part of it was when we passed right next to an Eagle who was hovering, facing the wind. We passed something like 10 meters away from this bird, and he didn't move... he just turned his head to look at us, like a cow watching a train
Then I made a U turn and the Eagle was still there, but this time he got bothered and flew away.
In FSX I fly gliders a lot. CumulusX is my favorite addon. It doesn't tranform FSX into Condor, but it gives a much more complete experience than default... and it's free
Concerning the Wingsuit, I'm actually learning to fly with these, in real life. I'm not using the same wingsuit as Jeb though, because I'm a total beginner. I use a smaller suit with smaller wings that allow me to recover to a "normal free fall" position in case I loose control in flight. Also, I jump from an airplane at 4000 meters, not from a wall at 4000 millimeters
Did you know ? Jeb Corliss had a terrible accident recently: he hit the rocks while trying to touch a balloon... Fortunately he survived, only his legs touched the rocks, not his upper body. He just had some broken bones... lucky guy. He'll be jumping again in some weeks/month without a doubt.
