Mission safety evaluation report for STS-33: Postflight edition

Abstract

Space Transportation System 33 (STS-33) safety risk factors that represent a change from previous flights, factors from previous flights that have an impact on this flight, and the factors that are not unique to this flight are discussed. While some changes to the safety risk baseline are included to highlight their significance in risk level change, the primary purpose is to insure that changes which were too late to include in formal changes through the Failure Modes and Effects Analysis/Critical Items List and Hazard Analysis process are documented along with the safety position, which includes the acceptance rationale.
