Let me make it quite clear at the beginning that I am not speaking as a paid agent or employee of any Hiller operator or representative, and that what I have to say is an expression of my personal opinions. They are based on over 2,000 hours of commercial operations with the Hiller 360 all over Europe, North and West Africa, during the past twelve months, when as Technical Manager of Helicop-Air (Paris) it was one of my responsibilities to ensure the efficient maintenance of three and sometimes four machines on high utilisation work.

Our efforts were directed principally towards such profit-making enterprises as insecticide spraying and dusting of cultivated crops, forests, swamps and river beds; the operation of a pilot and engineer training school; publicity flying for large manufacturing firms; a non-schedule passenger service; and sales demonstration.

These operations were frequently in widely dispersed, remote and inaccessible places where maintenance installations and workshop facilities were non-existent.
