>we've never lost a craft Can you explain? My comment was in the context of Columbia. “An investigation board determined that a large piece of foam fell from the shuttle's external tank and breached the spacecraft wing.”[1] I’ll give you the benefit of the doubt with your definition of “we”. But your tone seems to point directly to the types of biases I referred to. It’s worthwhile to research the history of the industry as an whole.[2] Prior to the disaster, do you know NASAs response? “Foam shedding happens all the time…it’s ‘in family’ and not a problem.” It was still out of spec for a good reason. The term from the investigation report is “normalization of deviance”. It seems even as technology progresses, we’ll still be anchored by faults in human psychology.
