DOW-UAP-D48, Department of the Air Force Report, 1996

Key highlights

• The report focuses on Mode-5 failure responses in launch vehicles.p.4

  “Mode-5 failure responses are much less likely to occur”

• It discusses the impact density function used in risk analysis.p.4

  “The impact density function used for this purpose contains two shaping constants”

• The report includes a failure history of Atlas, Delta, and Titan launches.p.4

  “An appendix to the report contains a listing and brief narrative failure history”

• It emphasizes the importance of modeling unlikely failures for safety.p.10

  “Such failures should not be ignored, since they may produce nearly all or a significant part of the risks”

• The report outlines methodologies for assessing failure probabilities.p.22

  “A primary purpose of this study is to develop estimates of the relative probabilities of occurrence”
