Just buy x-plane. You can do aerial refueling on x-plane as well as fly a full reentry of the space shuttle manually. Now with its new 60gig scenery package it kicks MS FS9 ass. But then again I still use FS9 because my pc has only a 60GB hard drive.
Quoting LawrenceMck (Reply 2): I think the new Captainsim C130 Hercules expansion pack has aerial re-fuelling in it. Might be a bit expenive though if you're only going to use it for in flight re-fuelling.
Can you point me to where this is? I have the package and have read the documentation and searched the tech support and can't find anything on it.
