And, last night I finished up the "bonus" diorama kit... a Movable Aerobridge (Passenger Gangway).
Usually these aerobridges are attached to a Terminal, but for the right diorama, this might be an interesting accessory.
You can reposition the swivel points of the walkway during assembly, so it can be built in a number of different configurations.
The supports are also telescopic, so the height at each end can be adjusted.
This is where I was unsure about how to shape the aircraft contact seal...rather than shape it to an exact fuselage,
I decided to give it a slight bow, as if its not quite fitted tightly to a fuselage...that way it should work with a variety of aircraft.
