Does Vashon Island even have an airport?
(Answer: Yes, although the FAA identifier is 2S1, and not VSH, which doesn’t quite have the same punch to it. Smaller airports serving general aviation (i.e. non-commercial flights and small planes) tend to have number-letter-number FAA codes, because there aren’t enough location-based letter codes to go around. How do we code empire into our basic systems and protocol?)
(Also: Pilots planning flights to 2S1 should be aware that there are OCNL LARGE WILD ANIMALS ON ARPT. Oh, rural Washington.)
