Edmundroland, working in the interpretation of numerical data myself, I'm of the same opinion.
Piggyback, the starting point in deriving probabilities is to determine ways in which we can arrive at a measure of likelihood. We can look at the relative frequency with which the event in question occurred in the past. The subject of discussion is the recently developed A380 and a single event where it is logical that combinations of events were considered by automation and on the ground back seat drivers to press on towards destination.
For most of those 30 years you mention Bergerie1, I'd imagine you enjoyed the independence to made your own decisions.
