“Tornado Alley” documents two unprecedented missions seeking to encounter one of Earth’s most awe-inspiring events — the birth of a tornado. Filmmaker Sean Casey’s personal quest to capture this event on camera takes viewers on a breathtaking journey into the heart of the storm. A team of equally driven scientists, the VORTEX2 researchers, experience the relentless strength of nature’s elemental forces as they literally surround tornadoes and the supercell storms that form them, gathering the most comprehensive severe weather data ever collected. This science adventure reveals the beauty and the power of some of our planet’s most extreme — and least understood — weather phenomena.
Sean Casey has directed a number of television documentaries (and even some music videos for the Violent Femmes) and stars in the Discovery Channel’s “Storm Chasers” reality series. To capture the extraordinary, first-of-a-kind footage in “Tornado Alley,” Casey not only had to learn how to enter a tornado, he had to design a vehicle that could take him there. In 2008, Casey introduced Tornado Intercept Vehicle (TIV) 2, built for one express purpose: to house and shuttle Casey’s camera (he and his crew call it “an armored tripod on wheels”). Built on a Dodge Ram 3500 platform, and surrounded by bullet-resistant windows and an armored steel shell, the 7-ton TIV2 has a third axle for six-wheel-drive capability, a modified 6.7-liter turbo-diesel engine, a 92-gallon fuel tank and a top speed of more than 100 mph.
