Yup. That was the risk taken at the time, on that day. It happened to work out. In freight dogging, you don't always have a perfectly plowed runway or otherwise ideal conditions; if you expect that, you're in the WAY wrong biz. You do what your knowledge and experience allows, without letting it become a safety issue. Exercise judgement. I don't "what if" the scenario, because it worked out. Take those lessons, good or bad, and put them in the SA bag of tricks for what to do in the future.
That, my friend, is called reality.
Not when enough ice is accumulating that it gets slung off. And this plane had continuous write-ups for prop anti-ice--inop.
