I've modified a JAL 777 into a hypothetical Pan Am 777. It looks pretty good. I tried to get all of the layers right but if anyone like RyeFly has something to say about it, or if you want a look at it, just E-mail me.
Sorry, I haven't uploaded it to a website because I'm a lazy SOB who makes modifying photos look like work. I know how to upload but don't feel like putting my e-mail address on yet ANOTHER mailing list or having to work through external links to free websites. But anyone who requests the pic will have it. Just e-mail me and satisfy all your Pan Am fantasies.
