The more I reflect on this purchase, sitting in my virtual cockpit of most aircraft I fly (B748, B772 and B789) I don't see ppl boarding (unless the jetway is in sight of the cockpit). Good one FSDT, you got me on this one.
Of course, the same could be said for AI, which seemed to be your original complain: having moving jetways docking on AI wouldn't be visible, unless the AI itself could be visible from inside the cockpit.
And, we already said we WILL add this as an option, but it will also require a SODE update, and we already discussed it with SODE author what would be the best way to have it but, SODE being a freeware product, we cannot just demand to appear immediately, but it will come.
