The shuttle IS operational, and it has been for a long time. An

What they could say is that the particular circumstance that caused the
crash had not been tested. The point is: there's always something that's
going to get you. With proper backup systems, one will occasionally
experience a "successful failure". In the other case:

Own up to the safety requirements or stop flying.


[I'd add "all" prior to the "safety"]

Where there's not a backup, that's where the input from the ASAP, etc. comes
into play, but the report is not worth much if it is not heeded.
