Hello All!
I've had a 1:400 scale model airport for a while now and I thought it'd be good to change it up from the pre-printed ground foil and the Gemini Jet's Terminal Building. Currently I have:
x1 First Choice 1:400 Scale Ground Foil
x1 Gemini Jet's 1:400 Scale Terminal

I started to Paint my own Ground Foil and figure out the style and shape of the terminal. The airport is a fictional Airport based in the West of Yorkshire, the name is a play on word with a cross between West and Yorkshire, I got 'Werkshire International Airport'. With mostly International Flights and some domestic flights to destinations mostly around Europe. Many airlines operate here including; British Airways; Jet2.com; America West Airlines; All Nippon Airways; Corsair (TUI); Caledoninan; Delta; Air Jamaica; Frontier. The airport will consist of:
x1 3, 285 yd Runway
x1 International Terminal
x1 Cargo Terminal
x3 Long Stay Carpark
x1 Short Stay Carpark
x1 Staff Carpark
x1 Ground Services Building
x1 Firestation
x? Aircraft Parking
x? RAF Hangers
x? Commercial Hangers

I have already started progress on the Aircraft Parking. I am painting the markings in myself. Please help me with any suggestions.
Thank You
