Vertical Horizons traces the rise of Okanagan Helicopters from its postwar roots in Penticton to an international operator. Drawing on company records and pilot recollections, it explains how early commercial work and mountain training shaped rotary‑wing techniques.

The narrative covers landmark moments—founding efforts in the 1940s, flood relief and crop‑spraying contracts, long‑distance ferry flights, Arctic surveys and offshore support—and the Mountain Flying School that trained generations of pilots.

Combining archival photographs with firsthand stories of rescues, unusual sightings and operational challenges, the book balances technical detail with human experience to document a distinctive chapter in Canadian aviation.
