Hard to believe that tomorrow will be the 20th anniversary of the Space Shuttle Challenger accident. I was in 11th grade when it happened. I remember walking down the hall from my locker in school when I saw a friend of mine who told me the space shuttle exploded. My first response was naturally disbelief, and it wasn't until I got home after school that I saw what happened on TV.
There's an interesting article over at MSNBC talking about 7 myths about the Challenger accident. I particularly like the last sentence of myth 7:
The disaster need never have happened if managers and workers had clung to known principles of safely operating on the edge of extreme hazards - nothing was learned by the disaster that hadn't already been learned, and then forgotten.
