<p>[QUOTE=&quot;CamaroDMD, post: 3730968, member: 5233&quot;]The real problem was normalization of deviance.&nbsp; NASA and Morton-Thiokol knew that the O-rings performance varied under different conditions and designed their launch perimeters accordingly.&nbsp; But, as they become more confident...they let those standards slip and little and nothing went wrong.&nbsp; O-ring blow-by was seen during the second shuttle launch (STS-2) but nothing bad happened.&nbsp; There was serious O-ring leakage on STS-51-C in 1985...but nothing bad happened.&nbsp; These issues were well outside of the established safely perimeters...but nothing bad was happening.&nbsp; They become complacent...then something bad happened.</p><p><br /></p><p>There is actually evidence to suggest that despite the failure of both O-rings in that joint, <i>Challenger</i> still might have made it into orbit.&nbsp; An oxide layer formed and sealed the leak.&nbsp; However, the most severe wind shear ever recorded on a shuttle flight to date also occurred during the launch and is believed to have disrupted the oxide layer.&nbsp; I have often wondered that if the shuttle had survived and the severity of the leak been examined...would they have finally stopped and fixed the problem or would they have continued flying because once again nothing bad had happened.</p><p><br /></p><p><br /></p><p>I 100% agree.&nbsp; Werner von Braun was a critical part of our space and ICBM programs.&nbsp; Not going to say anything otherwise.&nbsp; I just don&#039;t see him ever being on a US commemorative coin.&nbsp; Frankly, I don&#039;t know if he would have escaped the gallows at Nuremburg had he not had a useful skill.[/QUOTE]</p><p><br /></p>
