"After a long work, a group of retired Nirvanair employees restored an old Douglas DC3 we used to fly back in the days. This plane has been modernized to fulfill customers' expectations nowadays. So if you want a flight for your honeymoon, the old Douglas DC3 is made for you!"
This livery is usually made for the one who wants to fly something different. So please, enjoy and have a good flight.
Regarding the installation, you only need to unzip the file directly into your community folder.
