[10: aviation, airports, flying] The old warehouse creaks and groans as the sun hits it. The smell of grease and cardboard wafts from all sides, parts sitting in box after box, shelf after shelf, stacked twenty five feet up into the steel rafters of the building. A staccato voice rings out from the small workshop in front, asking for some small part or tool to finish retooling a piece of equipment that ceased manufacture twenty years or more ago, the manufacturer being bought by a larger company, spun off, bought again, names changed. Parts get counted and recounted, quality checked, boxes carefully repacked, then loaded for shipping. The warehouse contains, in parts, easily a hundred airplanes. No voluminous wings or body parts, but every piece of inner workings of almost every non-commercial plane made since the end of World War II. Parts bought at auction years prior, carefully catalogued and stowed, and like the manufacturers, bought, spun off, and bought again, names changed but, in some essential way, the same as it always has been. Some of the most valuable parts are name plates -- not the engine or the pumps or rotors, but just a square piece of brass with screw holes at the corner and a serial number etched into the center. You can replace every part on an engine and it'll be the same engine in the eyes of the government, until that name plate gets changed. It's not a part needed to fly, but no plane will be flown without one. They'll fetch a few thousand dollars for the name plates to some models. Parts get shipped off to repair houses in California, Florida, some overseas to Israel or Japan. Engines get rebuilt, pumps overhauled, fuel systems checked after every flight. Every screw is catalogued, every pin, seal ring, and name plate, with a master checklist for every model. There's a reason air flight is safer than driving: No motorist puts this kind of care into their car. Not even the obsessives with their shiny sports cars.
