hi there!

the thunderchief can be found here (I think) and certainly at nodes.com aka flightsim.com.
I think thunderchief was made by Mr. Ito, who made such good models as EE Lightning and others...
The F-111 is a real problem, the Aussies are doing one a very good one but she has no release date  , there is a payware F-111 from Alphasim, but sure is out question, at least for me, ok?

cya!
