Has there ever been an F6 tornado?
There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.
