Hi, All -
My first job out of college was working at Rocketdyne's test site near Santa Susana doing quality control analysis of the fuels used to test their prototype of the Lunar Excursion Module, so I'll never forget twenty years later being awakened by our radio coming on at 7:00 am on January 28, 1986 with the unbelievable (to me) news that –
in spite of below-freezing weather the night before – NASA was going to go ahead with the planned launch of the Challenger space shuttle later that morning.
"Those @#$%& Idiots," I said to my wife,
"All they need is one little crystal of ice in a critical relay and that thing is going to fail!!" I almost called my boss to tell him I'd be late for work 'cause I was going to stay home to watch the Challenger blow up. As it turned out, I was wrong about the exact cause, but sadly correct about the end result
. . .
