I was a passenger in a jet the other day and we would fly to the boundary and the plane would instantly turn 180 degrees.  I was thinking "WTF" and I watched the minimap.  We appeared to flip instantly 180 degrees when we hit the boundary lines.  I have now noticed this at least 3 times looking at jets on my maps.  Has anyone else noticed this?  Is this a bind, technique, programmed buttons/joystick, hack, or what?  I bought the 3d Extreme joystick and I can't get a jet to do that.
