I drive to some pretty remote places storm chasing, and use a Cradlepoint CTR350 with a Verizon USB727 aircard hooked up to an external wilson mag mount dual band antenna. This is about the best you will do without using expensive satellite.
That film you are talking about was the Kansas Turnpike/El Dorado Lake Tornado. The video was all for dramatic effect - If you look at the lines in the road in the video they aren't travelling more than 35-45mph.
Quite a memorable video, and probably the best that crew ever shot. It's being remembered almost 18 years later!
Be prepared for long hours in the car, clear sky busts 1200 miles away and a lot of gas station burritos. Storm Chasing, while fun, isn't as glamorous as Discovery has made it out to be.
Consultants are mystical people who ask a company for a number and then give it back to them.
