Oklahoma City FSDO needed a DC-3 "specialist" for certification flight checks with Cascade Airlines, a Part 125 operator who, curiously, didn't actually operate in Oklahoma … nobody seemed to know exactly who they were and where they did fly. But for right now the airplane and pilots were in Guymon, Oklahoma. Having spent a considerable chunk of time in Oklahoma City at the FAA Academy, I long ago concluded that Oklahomans are really, really nice people who live in a really, really dreadful place. But, hey, Guyman might just be interesting … way out in the Panhandle, a long way from, well, from not much of anything and about the epicenter of the 1930's dustbowl tragedy. Anyway, this was about flying a DC-3 so of course I'd go to Guymon.
