Nice!
For myself, once information began appearing on the internet about ekranoplans I went on a mad spree looking up everything I could find about them. This lead to wandering through a whole field of Wing In Ground-effect vehicles. While we typically hear about the Soviet WIG vehicles, there's a slew of designs in the civilian world that we rarely hear about.
China has also experimented with wing in ground effect craft but on the civilian front (some designs are however, offered for police or military maritime operations).
Where it gets interesting for us as gamers though, is that Germany also designed some small WIG craft for civilian use. The first design was produced in 1970 and the second design in 1977. Further developments were pursued up to the early 2000s but some of those designs were produced in the 1980s and early 1990s. The company behind all this, Fischer Flugmechanik, was located in Mönchengladbach in West Germany and as far as I have checked, they were still in business after 2011.
These smaller WIG craft make for some unusual vehicles for the PCs for a particular adventure or as something a little strange for the PCs to stumble across.
Some links for those who want to find out more or want to convert some of these smaller WIG types to game stats (although the early designs were typically two or four place only, they could carry approximately 200kg of cargo): -
