I took some pictures at Oshawa Airport last weekend. You can find them all here. The airport has a bunch of old classics hanging around.
oshawa_airport/DSCN0382This DC-3, and another that has the Bassler turboprop conversion (which was in the hangar with one engine off), are used to fly cargo down to research stations in the Antarctic. I beleive they also fly cargo for the local GM plant.
oshawa_airport/DSCN0383There are two AN-2s there. I don’t know what they are used for.
oshawa_airport/DSCN0391This is the other one.
oshawa_airport/DSCN0390A Beaver. On floats. It doesn’t get any better than this. Unless it were mine.
