The Shimmy is the name of a dance that has its roots in the late nineteenth century among America’s black population, and which subsequently became popularized. This dance consists of shaking your shoulders and hips, with arms raised, but in aviation, the shimmy effect can be annoying and even dangerous. And pilots are not the only ones who don’t like it. The shimmy phenomenon can also concern motorcyclists.
