When I bought the DC-3 way back (2002) it was CD.  Same for BT a few years back.  Now I see that only the TBM is available on CD.  Does that mean I need an internet connection etc to install the DC-3 if I bought the FS9 version? 

The MAAM-SIM CD versions of the R4D and B-25 are no longer produced.  You don't need an internet connection to install them, but you do to download the packages.  I guess that is a Catch-22. But once you have the installer, it can be saved as a back-up indefinitely, but the DL link itself expires after 48 hours. All the additional content on the CDs is available from our Free Stuff Page.
