That is one of many storm chases I have been on. This tornado was the satellite tornado near Protection, Kansas on April 23, 2007. This tornado never struck the town of Protection directly but did strike some farms. The larger tornado is pictured below. As far I know, nobody was injured or hurt in either tornado but if you watched the Discover Channel "Storm Chasers", they attempted to get their TIV (Tornado Intercept Vehicle) inside the larger tornado but was unsuccessful. The TIV is in conjunction with research with the University of Oklahoma School of Meteorology and NOAA (National Oceanic Atmospheric Administration) to intercept a tornado and gain live footage from the inside of a tornado. Personally, I think it's a suicide mission to ram a vehicle into a tornado but if it will aid in advance warnings and there is someone willing to do it, you have my blessings (and prayers)! I think it's a joint scientific / private venture to get this footage from inside the tornado. I've seen the TIV on several of my storm chases over the last few years. I always have a good feeling when I see the TIV or DOW (Doppler on Wheels) on my storm chases because that normally reflects that I'm thinking right when I prepare my personal forecasts for a storm chase.
