On August 11 I happened to be passing by the airport at Chester, in northeast California. It was 6 p.m., quitting time, and the U. S. Forest Service helitack crew was walking over to their cars, but one of them was nice enough to give me and my motorcycle riding partner a brief tour of the three Type 1 and Type 2 “restricted use” helicopters they were managing. The term “restricted” means they are not approved for transporting passengers.
