The Challenger disaster was COMPLETELY PREVENTABLE.

Completely preventage.

The families of the astronauts and crew that perished that day felt the program must go on in the face of failure. At the time they expressed this it was in grief. They would not know until some time later their loved ones were lost when it was completely preventable.

It is unfair for those that lose family to ask them to go against the 'spirit' of a noble program when that is all they have to hold on to. They should have the memory of those they love intact as they need it to go on this world. It is up to the rest of us to see past the incompetency and deal with it.
