I can't stop talking about the airports designed by this group. Not only are they extremely detailed for a freeware addon. They have plenty of eye-candy to go with them. Some of the airports come with ground vehicles that approach your specific aircraft as set by the nav2 radio freq. While some of set ups for aircrafts that park on the tarmac away from the gates. The jetways roll up to the aircraft as it does in real life.
The Airports are very colorful in design and the animation of traffic around the airports bring it to life. Don't get me wrong there are plenty of scenery that you can find that may look better then this (Boston Logan V.2 for example). But these guys take it to the extreme with animation at the gates and around the airport.
This shout out definately is deserved for all the work they put into their scenery. I encourage them to create more work and to even try projects outside of Italy! If I had to actually pay for scenery files, I would invest in these guys because their stuff is that damn good!
