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.
The body of the plane is built with five seats for passengers. The wings are added next with what I think are filler stickers added to the top of the wings. There is a small galley with sink and oven in the front of the plane right behind the cockpit. The cockpit uses only one sticker to show navigation equipment - the other is printed, which is always welcome (though not a new piece). A lavatory is installed in the back, and then the inside is complete. There is an odd choice for the door to the lav - a swinging door. Not much opportunity for privacy!
It’s always tough to sum up a set that has the sort of price tag that this one carries; because it doesn’t necessarily offer the collectors value that a Marvel or Star Wars set will offer, it can be a little harder to justify an outlay on, in this case, a few planes and a aircraft hangar. However, if you have a love for the City range, whether it be a nostalgic look back at your childhood, the general consistently-superior design of the range, or simply because your kids want an airport to build, this one has to be recommended. Once I finished building this, I set it up in my daughter’s bedroom, and the overjoyed expression on her face, followed by the extended time taken to play with the planes and flying them all over her room, made every single minute of the build worthwhile. Watching her swirl around her room – and later, the rest of house – clutching the planes and bringing them in for landings into the hangar, reminded me of why I fell in love with LEGO in the the first place; imagination.
If you don’t own Black Panther Pursuit or any of the sets that included Captain America, I guess it would a plus getting the both of them in this set but Super Heroes collectors tend to be completionists, so I think that scenario will be particularly rare. I guess you could always sell your spares on the secondary market, but really, who wants to do that?
