National Geographic: Inside the Mega Twister - Season 1 (2015)

INSIDE THE MEGA TWISTER On May 31, 2013, National Geographic Explorer and renowned storm-chaser, Tim Samaras, sent a tweet saying Dangerous Day ahead for Oklahoma. Within 90 minutes the most extraordinary in the history of tornadoes he and his Twistex team were dead. The thunderstorm that struck El Reno, Oklahoma, on that day defined superlatives. It was the largest, one of the fastest, and - for storm chasers - the most lethal twister ever recorded on Earth. In this new film we unravel the tornado and tell its story. While it includes many first-hand accounts and harrowing videos from scientists and amateurs in pursuit of the tornado, it was also probably the best documented storm in history and these clips are part of a unique and ever-growing database, documenting every terrifying twist and turn of the storm.
