Outside Centretown, but also new this year, is the Canada Aviation and Space Museum's Reserve Hangar, where they store all the airplanes and stuff that doesn't fit on the museum floor. Put on your 3D glasses and turn up your screen brightness and check out these aircraft photos!
The above photo is from inside the museum itself, which isn't part of the free tour (but it's a great photo, isn't it?). All the other photos in this post are from a tour I had the fortune to attend a couple of months ago.
In the photo below, immediately behind the tour group is a wooden full-scale model of a forward fuselage for Bombardier's CSeries aircraft.
