Backstory
(3 years ago)

1 hour after takeoff, a pax in first class went to get up and use the rest room, and boom, passed out cold on the floor. Hit the ground so hard it shook the whole airplane in flight. We initially thought the nose gear dropped or something...She vomited, slowly came-to, got her upright and sat her down, no MD on board. We declared an emergency, diverted (tried 3 different airports), got her on an ambulance, got fuel and paperwork (and coffee) and off we went. End of the day, Captain filed an incident report with the company, sent me what he wrote, and to my knowledge that was the last we/he ever heard of it.

Fast forward to today... here's my question. On an interview, should I even use this as one of my "bad day" stories if I said NO to the "any accidents/incidents/violations" question on the application? Or would this raise some concern? It doesn't really meet the requirements of an NTSB notification (no broken bones, wasn't hospitalized more than 48 hours). Just worried they may think I was trying to hide something by not disclosing it, but I don't think there's anything to hide. Better to ask for forgiveness than for permission I guess? Thoughts?
