Prof. Richard Fevnman 1uvas a member of the commission formed to determine the cause of explosion of the space shuttle, Challenger in 1936. He suspected that the low temperature of takeoff caused the CI rings to fail. He published the data on temperature versus the number of [IIring incidents in 24 previous space shuttle flights. These data are tabulated below. Inge?\" Temperature {Fahrmheitl I! BE 5? E? 6?
