Note to rails: Do not dogfight in an F16 after a long trip on the road and then expect to get any sleep when you go to bed. Jumping ahead in the flight simulator serves a purpose but jumping ahead on a train simulator seems to be contrary to the focus of the program.
I even have some difficulty staying with Falcon 4.0 when there are long distances to fly. Sitting at the computer to do the same thing has little appeal. I get to spend 10 or more hours a day doing MSTS with the real thing.
