Thanks for your comments!
I used sprayable glue to fix the grass. These aren't mats as I don't like the edges created by cutting them.
The whole airport except the buildings is made of wood (I think it's birch wood). I draw the apron markings directly on the wood with ballpoint pens.
Fot runway lighting I used fibre optics, the lamps at the parking positions are scale Z model railway lamps.
Well, it's not really based on another airport. The terminal design resembles Frankfurt, but unfortunately I didn't have enough space to create the REAL Fraport. I would have LOVED that!
Maybe at a later time....
I just tried to show as much planes as possible without losing realism.
I'm happy that you like my work, as it took nearly a year to complete it. Will try to post a overview shot today.
