transmissions don't have to be perfect, the certification rules don't require zero failure rate, just one low enough so that those designing and certifying it will have likely retired before the first failure occurs
What repercussions are there for some "Crat" in a Government Certification Agency that signs off on a bad design? Did anyone jump out of a hi-rise window over the Comet, the DC-10, Air Bus Pitot tubes, the 92 Gearbox?
Any ritual suicides anywhere we haven't heard of?
At best they retire with a full pension....worse case they stay on to commit more murders....then retire with that fat pension.
