@FH1100 Pilot: It seems you never did this kind of work. It's quite usual that the site you have to work at is downwind from your take-off point. 2nd is that you have not much choices in regard to the landing site. Landing sites have to be accessible for big trucks, the helicopter etc. etc and landowners or forestry people don't like to cut trees to provide you with more then minimal space neccessary. Therefore you sometimes have to deal with tailwind conditions. Believe me I know what I'm talking about. I did this fertilizing job for about 8,000 hours.
The only you may blame the pilot for is maybe not checked the aircraft thoroughly enough or to fly in heavy snowing (icing) conditions. But personally I don't think so. These guy's up there in the north know what they are doing.
Always happy landings
