Political Factoid
"NASA entered the [Space
Shuttle] era confidently,
anticipating that the odds
of a shuttle being destroyed
during flight were around
1 in 100,000.
"The space agency reevaluated
that risk, .. after the Challenger
disaster [in 1986, and estimated]
that the shuttle had carried a
1 in 100 chance of disaster."
