THE spinning tests conducted at the Keystone plant were started in a frantic effort to find an easy cure‐all for flat spins, in the same manner that the alchemists of old tried vainly to find the philosopher's stone that would perform the transmutation of elements. It was only after all the prevalent theories on causes of flat spins were tested that a real intelligent investigation started.
