Correct - the hanger can only accommodate the biplane. That having been said, in order to accommodate the other aircraft too the hangar would have to be huge, with an enormous footprint, and a substantially increased parts count. As a result, I'd estimate a price up to double the current RRP which I suspect few of the target market would pay. LEGO therefore got the size of the hanger right IMHO.
Compared to other major European hub airports, like Charles de Gaulle or Heathrow, CPH has a similar number of connections, but is much smaller in both actual size and passenger volumes, and can provide a calmer, more pleasant experience. Its location in the south of Scandinavia makes reaching most European destinations reasonable, and flying to destinations in the Baltic region and in Eastern Europe generally only takes half the time as from major hub airports in Western Europe.
Bag 7 finished off the front facade adds in a metal detector and the baggage check-in station. I guess you enter from the right and then maybe the revolving doors are where you can walk out to the plane. I'm not really sure anymore. The conveyor belt is a nice addition to the set for playability and is set up so you can pull the baggage cart right next to it.
@josekalel: I think the size of the terminal is kept in check for price reasons more than anything. This is a $100 set, and while bigger and pricier City sets exist, they tend to be few in number. What's more, the disadvantage to having a plane wide enough to seat two rows of passengers is that it inevitably takes up a big portion of the budget even for a larger set like this one. If the set were just the airport with no plane, then the terminal could probably be around twice this size at the very least… but then the set would not offer such a complete play experience.
Copenhagen Airport is a compact airport with two terminals for check-in, but with a common post-security departure and transfer area, thus making transfers very smooth. The airport handles in excess of 25 million passengers a year, which puts it in the same league as Zurich and Vienna. It has also consistently topped the charts for Nordic airports, serving as a European and intercontinental hub for all of them due to its location.
Colour-wise, it is mainly yellow, with only a dash of green and red, and a little more white, there to break it up. The worker has space to stand and drive the vehicle, and has a walkie talkie attached on the side of the car. Around the other side is a coiled-up, what I assume is a, fuel pump. It looks pretty good when coiled up on the side of the car. Stickers come into use again here, this time for the number plates.
