Below is an excerpt from an article in The Bulletin:
…The planes were part of a $5 million program to beef up the firefighting fleet in Oregon this past year. The agency was able to move the small tankers around the state when needed. Over the course of the fire season, they reloaded in John Day, Medford, Roseburg and The Dalles. But primarily they flew in and out of Prineville and Redmond, carrying 71,784 gallons of retardant from Prineville and 48,977 from Redmond.
Contracted with the state, the planes that flew out of Prineville belong to Air Spray, a Chico, California, company. Built by Texas-based Air Tractor, they cost $1.7 million each.
