My first job flying transport category airplanes was with Austin Airways in 1967 and we flew scheduled airline flights out of Timmins Ontario seven days a week year round as far north as Cape Dorset.
Our main aircraft was the DC3 but we did a lot of the flying using the PBY for water operations in the far north.
It involved a lot of IFR flying using mostly the ADF for approaches although we sometimes flew south where there were full ILS facilities.
In the winter it could be brutal getting the airplane put away for the next days flying putting the engine covers on and attaching the Herman Nelson and then putting wing covers on to protect the upper surfaces from snow and frost.
In the morning we had to start about an hour before take off getting the Herman Nelson going and pre heating the engines.
Navigation was map reading when VFR and ADF and Astro Compass when we could get star or sun shots above the cloud cover.
Considering the environment we flew in it was amazing we did not have more accidents than we did.
Oh, I almost forgot to mention how difficult it was loading and unloading 45 gallon drums of fuel in the DC3 which sat on a tail wheel.
Also during the winter we used wheel skis for off airport operations.
When the Twin Otter was built we thought we had died and went to heaven it was so much more easy to operate not to mention the turbine engines were so much more dependable.
I started on the Twin Otter in 1974 on floats.
Back to hand spanking the DC3.
It was easier to start it using 25 feet of rope, a Ski Doo and two people, one to drive the Ski Doo and one to pull the prop through to get it over the first compression stroke so the Ski Doo could keep it turning.
But for sure hand spanking it always worked.
Speaking of hand spanking it.......
