Crop dusters, those daredevil pilots of the workaday world, are worried about the recent rise in unmarked towers that wind energy companies are planting across rural America to survey fields for possible wind farm sites, according to the New York Times.
These so-called meteorological evaluation towers (METS) are made of metal, stand nearly 200 feet high, are frequently, don’t appear on flight maps and are frequently unmarked — a dangerous combination for planes flying low and fast.
These towers are just short enough to avoid FAA mandated markings. Since 2003, five pilots have died after crashing into METs.
