Storm Chasers Risk Their Lives to Gather Research While some dogs like to stick their heads out of car windows at eighty miles an hour some people. Like to skinny dip in thunderstorms and some meteorologists. Like to get as close as they can to monster tornadoes. But after the tragic loss of three Storm Chasers in this -- spate of Oklahoma twisters. -- their exploits up to adrenaline addiction. Seems really unfair as ABC's own storm chaser ginger -- tells us the man who lost their lives are driven by the pursuit of life saving science. And sometimes even most cautious professional is no match for mother nature. Right yeah. -- It was a cruel twist. The second deadly storm to -- local.

The Storm Chasers are -- special breed of scientist when everyone else is driving in the other direction they hurl themselves directly into the heart of the storm. -- -- -- They say their mission is to better understand nature's destructive and deadly force. But this tragedy has shaken the storm chasing community to its core and left many wondering how it could have happened to this meteorological hero. -- get a story that news is. It's horrifying it's like a nightmare. Reach him -- was also in El Reno and -- -- Carl well -- for a -- work together on the Discovery Channel show storm chases. We knew Tim as one of the most cautious chasers in the business. There's some that doesn't make sense because he knew exactly it is doing and he's always been controlled -- just doesn't make sense something. It's not right. Tim with a two pioneer in the field who -- technology that continues to help -- measure and predict tornadoes. His quest to learn and inform always inspired him to give states. I had the honor of joining him on a recent expedition to study his other love lightning. -- -- -- -- How beautiful. For the price measurements on teased him it's really easy -- your car -- -- go here -- with undergo park up next to a cheering. Well it's not basis sometimes is almost as difficult. Chasing a trail is as good lightning storm. I'm gonna go see -- -- -- always on the cutting edge Tim built this ultra high speed camera in the hopes that he could capture the birth of a lightning strike there's actually 82 campers on his instrument you're taking. One picture of the lightning and one -- -- second steps time. -- and -- percent critics said it was impossible but him has never been one to shy away from town. -- to give up until this is done especially as the naysayers tell me this can't be done that distracts me harder.

Starting lightning starting tornadoes. Are warranted final frontiers in the urology you know -- of these things there because -- so fleeting they're so very difficult to study. Do you have to get up close and you have to collect imagery you have to collect data. To feed these models and maybe a computer prediction model -- tell you down the road how much lightning in particular thunderstorms can generate. It's that philosophy to get close to storms that drives meteorologist like us to keep chasing despite the obvious risk. But now some say tornado Alley is saturated with an increasing number of untrained un educated Storm Chasers. -- -- blamed for storm chasing traffic jams and unsafe conditions in the past officials say that might have been the case Friday night. I think it's probably -- the amateur Storm Chasers that calls more of an issue because we've got a lot of people that need to be out there the first responders. News organizations and legitimate Storm Chasers they're trying to get information out. But legitimate storm chasing scientists like ten and -- to -- aren't just after the thrills in 2007.

His nephew and their colleague Carl -- died doing what they love the biggest thing that he could have done was he gave his life for others. Oh look back. How beautiful. And pretend it was my night -- he has to kind of passion that fueled his every chase. I don't know how many storms I've seen in my lifetime that every single one of nice of him pretty excited.
