Hi Kevin,
I don't think the repaint is available at Avsim...you can find the repaint at flightsim.com. The file name is 'DC910TWA.ZIP'. The SGA base file name is 'SGA910.zip' and I imagine it can be found at most major FS sites.

I agree that the "twin-globe" livery was TWA's finest. I grew up relatively close to a TWA maintenance facility so I'm rather partial to TWA.

At our local pizzeria, when I was a kid, I once came across a truck hauling a tarp-covered jet engine for TWA. The truck driver had stopped for lunch. Of course I couldn't let the opportunity to see up-close an un-cowled jet engine sneak past. I felt just like a kid peeking under the circus tent, gazing at that engine. Ahhh, memories. ;-)
