Been away for a few days, so only just picked up on this thread. I am happy to "come out" and admit that I have been a keen flight-simmer since the days of the Commodore 64 - and YES, that does make me over 35!! There are a lot more of us out there than people realise - else why would M$oft continue to support the genre? For all things FS related, you can't do better than go here: www.avsim.com Anyway, back "on-topic" ... ... I have been using on-line "Real World" weather for so long that I never stop to think about it these days - it's just there. And, using something like "ActiveSky 2004", it is extremely realistic and capable of some stunning effects. Look here: http://www.hifisim.com/activesky5.htm to see what I mean. Imagine those skies applied to a "dynamic" Vue scene - it would react to the real weather in whatever part of the world that you choose to set it. Just picture a stunning rocky cliff / sea vista that moves from stunning sunrise through wispy clouds and sea fog to stunning sunset - all dynamically! The technology to do this has existed for years now - it's been in FS for about 5 years now I think. All that would be needed would be to enable the technology within Vue. No doubt easier said than done, but if it can be enabled within something as massively complex as a Flight Simulator, why not elsewhere? Ah well, we can but dream!! :-) Bernie
