Description of Driving Event:
The failure analysis of a temperature probe for a cryogenic hydrogen system was investigated by instrumentation systems engineering for effects on the instrumentation system (loss of output from one temperature sensor which is minor). The potential effects of the defective weld (piece of the probe entering the liquid hydrogen system) was not recognized till later as catastrophic.
