@randomstormofficial: They measured this tornado's winds from film alone — without a single sensor inside it. Scientists tracked debris frame by frame through the 1973 footage and calculated winds up to 185 mph. Just a camera, a reel of film, and math. Real footage filmed by NOAA NSSL researchers, Union City 1973 (public domain). Full breakdown on my page. #tornado #Viral #Nature #Storm #Foryou
