![I have to think that because NASA chose to co-author this paper [LaDochy et al., 2007] with researchers at California State University, that some of the statewide "global warming as man-made problem bias" crept into the thinking for the purpose of this paper, i. e. "we need another study to show that its getting hotter so action is justified." (Anthony Watts)](https://cdn.quotesdtb.com/img/quotes_images_webp/49/anthony-watts-action-bias-768049.webp)
The motives for conceiving modern systems engineering are to be found, at least in part, in past disasters. Arthur D. Hall III [1989] cites: the chemical plant leakage in Bhopal (1986); the explosion of the NASA Challenger space shuttle (1986) and the Apollo fire (1967); the sinking of the Titanic (1912); the nuclear explosion in Chernobyl (1986) and the disaster at Three Mile Island power plant (1979). He cites, too, the capture of markets by Japan from the U.S., the decline in US productivity and the failure of the US secondary school system. He identifies the millions of people dying of starvation every year while other nations stockpile surplus food, medical disasters such as heart disease, while governments subsidize grains used to produce high cholesterol meat, milk and eggs; and many more. One implication is clear: systems engineering faces challenges well beyond the sphere of engineering.
Derek Hitchins
"You can never be too safe." Yes, you can. How many of us bother to inspect the hydraulic brake lines in our cars before we start the engine and head off to work? Doing so would be safer than simply assuming that the lines were intact and driving off. After all, prior to launching a space vehicle, the people at NASA make no similar assumptions. They go through a countdown of all systems, taking nothing for granted. Erring on the side of over-caution is costly, and so is erring on the side of under-caution, though for a given choice, one might be costlier than the other.
Walter E. Williams
