Apollo 204 Review Board Members identified the conditions that led to the disaster, and then
they asked the question of how these conditions came to exist. After carefully considering, the
Board concluded that in its devotion to the many difficult problems of space travel, the Apollo
team failed to pay enough attention to certain mundane but equally vital questions of crew
safety. The Board's investigation revealed many deficiencies in design and engineering,
manufacture and quality control. When these deficiencies are corrected the overall reliability of
the Apollo Program will be increased greatly.
