I'm not sure what to make of the set yet. I like the planes (although that biplane really doesn't need the bubble canopy). The idea of adding a hangar is interesting and I don't mind that it's a bit open. But the fact that it'll only house one of the three planes is annoying. Having said that, I'm not sure what you could do about it. Tripling the hangar would make it big and boring and push the price up. Could they have done two planes and a double hangar?

City is the thematic title under which most Town-related System sets were released from 2005 and onward. There are numerous sets that are associated with Construction, Police, Fire, Emergency, Train, Airport, Transportation, Cargo, Traffic, Coast Guard, Farm, Great Vehicles, Mining, and Space. European catalogs featured another theme called City in the years 1999 to 2000, which was referred to as City Center in American catalogs.
Every good airport needs a hangar for the planes, and this is no exception. The satisfactory hangar included here does come across as rather basic, and while it doesn’t detract from the overall package, it isn’t going to swing your decision over whether to purchase this (and truthfully, I think you would have already made that decision before you come to the hangar). The design itself is simple, with the build unlikely to take you more than 10 minutes. That being said, it is a well-built piece and doesn’t feel flimsy, which was the impression I had when I first saw a picture of it. The criss-cross pieces towards the base give it a firm foundation, and there are plenty of long pieces which add further stability to it. Plane-wise, it is best suited for the old-fashioned vehicle, with the orange colouring in the design going well with the plane. Only a couple of stickers in use here, with just the AIRSHOW HANGAR words needing to be added.
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.
