A contract our company had back in the late eighties required us to fly under a span in a Provincial park so as to get our product on some trees which were on a small outcropping under the bridge, I recently drove over the same structure and the trees we sprayed are now beutifull to look at and also have achieved the aim of preventing bank erosion, now gues what? TC had to issue a low flying waiver for this contract as it meant flying almost down the main drag of a small village {and a 600hp Ag Cat tends to be a bit on the load side!} The inspector who issued this waiver did in fact work for us after he retired, dont know where he is located right now , but it would be nice to hear his take on this Im sure.
