Not about the UA flight, but the grandparent's first point. I can see how it's not simply superstition or theater. Critical info gets communicated either over fuzzy radio or 220 character ACARS messages. You wouldn't want to introduce into that context any spurious usages of phrases that would result in wasted time disambiguating whether a garbled transmission was referring to the Very Serious Bad kind of "crash" or referring to something comparatively trivial like the ticketing system being down.
