Thanks, two chai. Yes, the curve is a giveaway, but I had never seen a picture of Borden before. However, I immediately looked up what I knew to be the biggest early military airfield in Canada. How on earth did they manage to avoid the military obsession for straight lines and right angles? I can imagine the RSM having a fit.
BTW, a nice picture of the 504K, for which I have a soft spot, since both my grandfathers learnt to fly in them. However, the artist has managed to overlook the requirement for windscreens! For British readers, note the "Imperial" registration prefix for Canada in the 1920s - "G-C". I'm not sure when the switch to "CF-" happened.
Here's a quite difficult one (I think, but I imagine I could be proven wrong very quickly). Where was this nice art deco terminal? Extra points for identifying the aircraft with the two-row radials.
