I just came across this, a short documentary clip form Discovery Wings highlighting some of the development process for FS9, specifically the aircraft. It isn't very long or detailed (it seems like just a quick 3 minute preview for a longer show), but is interesting nonetheless. If anyone has a link to the full documentary, if there is one, it would be great if they could share it.

 

Thanks for the heads-up.

Very interesting. Would like to see the complete program (if it exists).
