Very cool. You can actually see the first of the North Central Airlines hangars on the far right side of the photo. This was torn down within the last decade. It looked like this:
(The Northwest HQ/hangars were on 34th Ave S where the Delta buildings now are. Of course, North Central (Herman the Duck) merged into Republic which then merged into Northwest in the 80s.
You can also see the old "Bloomington Road" alignment next to it, which is now Labelle Drive through the national cemetery. This was the original Fort Road/Ft. Snelling - Bloomington link before Hwy 5 was built.
Also interesting to see the old alignment of terminals/hangars on 34th Ave. The control tower is still there, as are a few other structures. But they've been very aggressive about tearing down old structures there over the past few years. I'm not sure if the Zantop Airlines hangar is still there, but it was up until a couple years ago.
