It's one of the first things most people think to try, but it's not something a serious training sim would want to encourage. That sounds fairly reasonable. However, as SimGear and TerraGear evolve towards general vehicle simulation, we will want to allow cars, boats, and trains to pass under bridges. It should be pretty easy to get this behavior. When you get the list of terrain intersection points, just ignore any points that are higher than you, and accept the highest point that is at or below the current vehicle elevation. I thought this was the way we had it working years ago, but that section of the code has been optimized several times since then ...

Curt. Could you add the feature to fly under bridges? I prefer having a realistic simulator that allows everthing instead of a simulator that is baby sitting me.
