Tim Samaras has been following his passion for storm chasing for 30 years. He has been able to mix his passion with his career as an engineer. He has successfully gathered scientific measurments from inside of tornadoes and holds the world record for measuring the lowest barometric pressure drop (100 millibars) inside of a tornado that destroyed the town of Manchester South Dakota on June 24, 2003.
Samaras has also built a special probe with cameras that are able to look inside of a tornado safely. He successfuly captured this in Storm Lake, Iowa on June 11, 2004. He also formed the research group TWISTEX
(Tactical Weather Instrumented Sampling in/near Tornadoes EXperiment).
