Where can I download this Boeing Business Jet? It is found at http://www.flightsimworld.com/forums/index.php?showtopic=10234 (Not the green plane, the white and red one)
I think this is your jet.
Take a look at the Kittyhawk's.
And here for Cantu's stuff.
Did you look at these.
Or, you can go here http://www.flightsim.com/ and feed in 737 kittyhawk, to 2004 jetliners in search. I came up with 96 aircraft and textures.
