With the same copyright on all three of those, I'm seriously doubting the authenticity. Nice digital editing, though. I could be wrong, but I don't think so.
Mmmmm I agree..That shape is not adequate with the theories of tornadoes forming..As to me it's fairly impossibile to have a similar shape even when the tornado is roping: to have a tornado like that, the storm, while the tornadic strucure is roping, should go ahead, then come back, and the come back another time and so on, and I think this is not possible in nature.
