Death of a Storm Chaser

Storm chaser Tim Samaras died Friday doing the work that made him so well-known: following tornadoes. Samaras was killed along with his son Paul and storm chaser Carl Young in Friday's tornado in El Reno, Oklahoma.

An engineer by training, Samaras was known for devising instruments that offered the first views inside live tornadoes. "We still don't know why some thunderstorms create tornadoes while others don't," he told National Geographic last month. "We're trying to collect as many observations as possible, both from outside and from the inside."
