The set contains six minifigures. Even though they all incorporate standard, unprinted minifigure legs together with commonly-available headprints, it appears that all six are unique to the set. First up are two members of the Ground Crew (below). The bearded guy has an orange torso printed with a hi-viz jacket, ID badge and red pen pattern. This has appeared in nine sets to date including all of the 2016 Airport sets plus 60080 Spaceport which I reviewed here last summer. His red construction helmet, which incorporates a pair of non-removable black ear muffs, has appeared in less than ten sets to date. The other member of the ground crew has a rather nice printed medium blue torso which is new this year and has only appeared in a total of three sets including this one. It features a shirt print which includes the Octan logo and a top pocket complete with a pen.
The final two minifigures are the Biplane Pilot and the intrepid Wing Walker. Both of these minifigures share the same white torso which is printed with a flight suit design overlaid with dark red and bright light orange flames plus a logo over the left breast. The torso design is superb and it can at present only be found in this set. Both minifigures are provided with a reddish brown aviator cap and dark bluish grey goggles, and the pilot (below left) also gets an alternative to this headgear in the form of medium dark flesh mid-length hair which has only ever appeared in five sets in this colour.
The remainder of the build is the control tower and terminal building. First there is a metal detector screener leading to the waiting/secure area of the airport, which seems taller than it needs to be for the minifigures. I think the same effect could have been made with half the height, except that would not allow for an impressive height for the overall tower. However it does seem to be similar to many modern airports with the high ceilings. This area also seems to be someplace to check luggage as evidenced by the rather nifty conveyor belt that comes in a full part. The moving parts of the set include a revolving door (a very tall one, for the first floor) that leads from the secure area of the airport out to the tarmac, and of course the conveyor belt.
