You did it at LSZH. Can't it be done again for FS9?
In Zurich, we used old style Gmax animations instead, which are of course much worse compared to the Simconnect method, that uses real physic-modeled vehicles, and it's much more powerful and result in more realistic path following.
So, in order to have them in FS9 in the newer sceneries, we should do an extra work for FS9 only, which will never look as good as in FSX, THAT'S why we added support for this feature in the FSX version of the Addon Manager in the first place, so we can have better animations in the scenery.
The fact FSX allows this, is one of the many reasons why FSX is better: we just can't stop progress, and keep using older methods forever, just to allow them to be ported back to FS9. The change has been gradual and constant so far so, the later sceneries are more FSX-centric then the earlier ones, and this is going to continue in the future.
