NASA, when they designed the Shuttle, forgot that during the Apollo and
Gemini flights, many things went wrong. The only reason the crew survived
was because of the toughness of the capsules, their simple designs, and
their inherent safety (no active stabillization needed during reentry).
Shuttle: 121 successful flights, 2 failures
Mercury: 6 flights
� � � � MA-7 - landed off course 402km, numerous issues.
� � � � MA-9 - many issues, helped lead to cancellation of MA-10
Gemini: 10 flights
� � Gemini VII - thruster malfunction nearly results in loss of craft and
crew. �Rest of mission aborted
Apollo: 14 flights (including Skylab and ASTP)
� � Apollo 1: Need I say more?
� � Apollo 8: ended up in Stable 2 position, making crew seasick until
righted
� � Apollo 13: Near loss of crew and craft in cislunar space
� � Apollo 15: One of three chutes failed leading to rough landing
� � Skylab 3; thruster leak, leads to possible launch of rescue vehicle
� � ASTP: Near loss of crew after landing due to intrusion of nitrogen
tetraoxide into crew cabin.
So a total of 24 flights compared to nearly 5 times that number.
So how's that track record again?

Ask me about lily, an RPI based CMC.
one should assume that flights near the begining of space travel have
more issues.
given lack of knowledge, like about the flamability of materials in a
oxygen rich atmosphere.
but as years go by experience should make things safer
