The diagram looks wrong to me. Although the sun is 93 million miles away, it is *much* larger than the Earth, so the Earth's shadow is a cone tapering *away* from the Sun. I'm not sure if this damages JD's argument about detecting Sun visibility for sensible aircraft altitudes (the atmosphere is a very thin skin around the planet) but if the sim were ever extended to spacecraft, we'd want to get the geometry exactly right. Maybe I'll fire up FG for August 1999 and see if it does solar eclipses :¬) Jonathan _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
