This is The Dominator from Tornadovideos.net. Reed Timmer and his team built this bulletproof truck (based on a chevrolet tahoe) for chasing into smaller tornados to filming nearby and to deploy camera probes in the path of the storm.
About this creation
The camera probe (orange) in the back
On the roof some meteorolical equipment: Warning light, radar, anemometer and a plexiglass dome with a camera inside
Thank you! But I can´t watch the show, because in Germany it´s in the pay tv. But im looking often at their home page and in the tornado season i´m often on their live page where you can look the livecam from the Dominator, when they are chasing tornados. Thats really thrilling. But the last tornado season was very sad (april 2011)
Remember all the tornado victims in 2011.
