I think your definition of aircrew and mine differ somewhat. In the military aircrew are defined as those that are employed in a role undertaken onboard aircraft. You are therefore considered aircrew when you are walking down the street or buying a pint of milk. She was not aircrew. Experienced passenger yes, but not aircrew.
I have over 20 years (and counting) experience flying military jets. I have flown quite a few passengers. Yes, I would expect them to say if they saw anything out of the ordinary. But the chances of any passenger noticing an anomaly on engine gauges before either a warning chime or me hearing something unusual I’d say are zero. Even if I was flying a formation take off.
I can’t keep banging on about it because it’s not really relevant to the conversation but you seem to think you know best when, in fact, you may not.
