During my time as an engineering student doing certain projects we had a tile on the wall which read (translated) "Because it was like that last year ..." to remind us to always check everything and not assume they did it correctly previously or it was a good idea. Maybe in their understanding it was correct, but you should never assume it is good for you unless you have checked it and you can explain why it is a good idea. This was not related to the challenger disaster in any way, just to show the ideas of the report are more broadly applied. > The Challenger disaster is a commonly used case study in engineering classes, especially when discussing engineering ethics or communication with clients/managers. Yes, and so is the Mars Climate Orbiter to some extend, though no ethical questions there.
