Butte County Sheriff doens't have any helicopters as far as I know, but they have a fixed wing. The 2 helicopters they are referring to are probably the CHP's H14 and H16 Astars based in Redding to the north but I think know what assets they have further south. Could have been they were fogged in or out on calls, here is the 407
