Space Shuttle O-Ring Failures
Description
On January 27, 1986, the night before the space shuttle
Challenger exploded, an engineer recommended to the National
Aeronautics and Space Administration (NASA) that the shuttle not be
launched in the cold weather. The forecasted temperature for the
Challenger launch was 31 degrees Fahrenheit—the coldest
launch ever. After an intense 3-hour telephone conference, officials
decided to proceed with the launch. This data frame contains the
launch temperatures and the number of O-ring problems in 24 shuttle
launches prior to the Challenger.
Usage
ex2223
Format
A data frame with 24 observations on the following 2 variables.
- Temp
Launch temperatures (in degrees Fahrenheit)
- Incidents
Numbers of O-ring incidents
