"F6 - Inconceivable
With winds above 318 mph (509 kph), F6 tornadoes are considered "inconceivable tornadoes." No F6 has ever been recorded and the wind speeds are very unlikely. It would be difficult to measure such a tornado as there would be no objects left to study. Some continue to measure tornadoes up to F12 and Mach 1 (the speed of sound) at 761.5 mph (1218.4 kph) but again, this a hypothetical modification of the Fujita Scale."
