Update: I noticed many of the links point to the AVSIM library even though they don't point to any liveries directly so I was able to search and find many liveries on AVSIM.  Of course, the AVSIM library search system is ancient and totally broken so the best way is to just use Google to search the AVSIM library for Captain Sim FSX Boeing 727 liveries.

Btw, I am absolutely in love with this old FSX airplane.  It's easy to tell that it was a labor of love by the developers and it really shows.

I originally purchased this plane about 4 years ago, but I finally decided to learn to fly it just recently.  I usually don't fly airliners a lot, but this one is such a joy to fly once I took the time to learn to fly it properly and learn all of the systems.  I know I will be flying this one a lot.

Thank you, Captain Sim!
