Borderline-insane tornado video!!!

Storm chasers Chad Cowan, Darin Brunin and Jordan Wrecke were in perfect position to document this amazing, photogenic tornado that occurred near Grainola, OK on February 27, 2011. The tornado eventually crossed the OK/KS border, and remained over open country for its lifespan. Chad shot this video with the Canon 5D Mark II with a 17-40mm f/4L wide angle lens. Like the opening shot? You can help send Chad to South America by voting in the National Geographic contest, below! We appreciate your support! www.nationalgeographic.com Prints also available at www.chasethestorms.com and http Chad will be one of the only chasers filming exclusively with an HDSLR this season! Expect more of the same from his future videos -- only closer next time!
