Highline: Pacific Northwest's High-Voltage Transmission System (1950)

"Highline," an overview of BPA's role as a transmission system operator, includes a tour of BPA's Ross Substation and aerial photography. It tells the story of building the transmission system in the voice of a self-titled "transmission man" who is taking his nephew Bill around for a look at what BPA is doing. There are appearances by Dr. Paul J. Raver, BPA's second administrator, and Sol Schultz, first chief engineer, as well as Abraham Osipovich. Osipovich made substantial contributions to BPA, including the innovation of vibration dampers on transmission towers, which help reduce wind noise. It was the first color film produced by BPA's Motion Picture Information Division and the final film written by information officer Stephen Kahn before he left the agency.
