Re:The article is mostly crap - re seals (Score 1)

In the full testimony given for the Challanger, it was noted that the program managers had serious concern raised by Thiokol engineers that they had never tested the O-reing seals at the freezing temperatures prevailing on the shady sides of the boosters. The PM launch deciders were apparantly reassured when someone said that the Titan launches with 'the same' O-ring seals, had survived launch at low temperatures. They were not told, that 'the same' seals had the V part of the seals pointing down on Titans, but pointing up on Chalanger.
