The California Department of Forestry and Fire Protection (CAL FIRE) operates an aerial firefighting air attack base at the airport with five aircraft based at the airfield. The typical complement of aircraft is one Rockwell OV-10 tactical (spotter) airplane, two Grumman S-2T air tankers, and one Sikorsky S-70i helicopter.[2] The base also hosts a helitack crew, a team of wildland firefighters who are transported by helicopter to fires. In addition to the firefighting mission, the helicopter is also equipped with a hoist for search and rescue missions. The Columbia Air Attack Base has facilities for refilling water and retardant on up to six firefighting aircraft, on rotation.[3]
The airport had scheduled passenger airline service operated by Yosemite Airlines, a small commuter air carrier which was based at Columbia Airport, from the mid-1970s to the early 1980s. According to the Official Airline Guide (OAG) as well as the airline's timetables, Yosemite Airlines flew nonstop and direct service between the airport and Sacramento International Airport (SMF), San Francisco International Airport (SFO) and Oakland International Airport (OAK) with small Beechcraft, Cessna and Piper prop aircraft.[4] [5] [6] The airline's route maps from this same time period also show nonstop service from the airport to Lake Tahoe, Modesto and Stockton.[7]
In 1999, Scenic Air, another commuter airline, was operating daily nonstop service between the airport and Oakland International Airport (OAK) with Grumman Gulfstream I propjet aircraft.[8]
The airport was used as a filming location for several sequences in the 1992 film Radio Flyer. [9]
