FYI, an older video for sure but interesting and educational.  If you have Amazon Prime's streaming service, this link will take you to "Mr Tornado", a feature on Ted Fujita, a world renown expert on tornadoes and damage assessment.   The video will be taken down at the end of this month (May 2022).
