Matters Discussed:

The organization and lines of authority in the Shuttle Program during its development, and the relationships between engineering, mission operations, safety reliability and mission assurance (SR&QA), and contractors.

The considerations that drove the evolution of the Shuttle design including, trade-offs involving budget, schedule, re-usability and weight; margins of safety and redundancy; and management of risk in a “system of systems.”

Shuttle design specifications relative to debris hits on the orbiter, and the disposition of in-flight anomalies through the problem reporting and corrective action (PRACA) system.

The challenges related to safely sustaining an aging aircraft fleet.

How the sociology of NASA as an organization and the normalization of deviance contributed to the Challenger launch decision and may have contributed to the Columbia accident.
