For the size, strength, and duration of that tornado, it is amazing there were no fatalities.
He actually did a great job telling the driver exactly what to do. You have no idea how difficult it is to get good tornado video up close on a storm moving that fast. You have to watch the radar to see storm motion, watch the tornado as it moves while expanding and retracting then also need to follow the GPS to make sure you don't take a wrong turn all while trying to keep the camera on the tornado and while the driver avoids debris.
Good to see them stop the chase as soon as they saw injured people. I can tell you first hand it is so freaky being the first one to drive up into the middle of a damage path with people stumbling out.
Not to mention being in mississippi or anywhere else in "Dixie Alley" the amount of trees and other things obstructing the view of storms makes it even harder to spot tornadoes
