Tornado Intercept Vehicle
From Wikipedia, the free encyclopedia
The Tornado Intercept Vehicle (TIV) is a heavily modified Ford F-450 truck used as a storm chasing platform and built by IMAX director Sean Casey. This heavily armored vehicle can drive into a relatively weak tornado (F0 to F3) to film it and take measurements. Some people may call it "Dumb and Dumber without the fur", quoting Sean Casey, because of its resemblance to the "sheepdog van" of that movie. The TIV is featured in a series called Storm Chasers which began airing on the Discovery Channel in October 2007[1].
Casey and his team are currently overseeing development of the second Tornado Intercept Vehicle, dubbed "TIV 2," to be featured in their next IMAX movie and the Storm Chasers series.[2].
