As ever I bow to your experience, but what if a distraction prevented the aircraft being flown, even temporarily, due to, for example, a dodgy and functionally unsafe connector coming loose during in-flight servicing? As in SI/CHK/57.
Surely there are some distractions which are more distracting than others, like the apparent loss of an engine control unit? What did the FRCs say about the DECU recovery time if the connector was disconnected, then reconnected? Or its ability, or that of the power supplies, to cope with a single or multiple temporary interrupts?
If, as the evidence suggests, the connector was to be checked every 15 mins, statistically there is a reasonable chance that a check was being conducted in the timeframe under consideration.
