Hello.  I have been looking for quite some time now. 

Aerion SSBJ

a supersonic Business Jet. 

There was one for X-plane 8 that I used to fly quite regularly.  I loved it.  I would love one for FSX.

if you are feelin' lazy.

Also, here's a link to their main page:

I would love to get some training behind this bird before I finish my real life training.  That way, someday, perhaps I can try my hand at flying the real thing.   

We can all dream can't we?

I don't know about that, but have you seen JakeF14's JBizz, http://205.252.250.26/cgi-bin/yabb2/YaBB.pl?num=1257675629/0, http://jdsmodels.yolasite.com/.

It will be for FS9 & FSX, and have a VC, http://205.252.250.26/cgi-bin/yabb2/YaBB.pl?num=1265100001. ; It's probably the closes you get to the Aerion SSBJ.
