Re. Fullwings about the flow simulation example...
I have learned (or was often reminded) that no simulation is really worth some real data. So what I would expect, if the situation is not clear by now (apparently it isn't), is that a bunch of aircraft of that type are being instrumented (sensors, etc) to provide the data that are missing today. If you cannot easily reproduce the event, at least be prepared to learn more, the next time something similar happens.
