Yes, when I was flying as an ER FO, I flew with a lot of self proclaimed DZers. When I asked one what do they need to retire and they said about twice this (showed me his Fidelity account screen. It was north of $3M) AND the pension restored.
I do not know where that came from, what his investment profile was, if he made wise decisions, etc or was lucky and bought at the bottom, didn't know.
I had also been shown a picture of his airplane, and his lake house (with airplane on floats) on the same trip.

I might hit $3M if I max out the contributions the rest of my career, and that's with 5% performance over inflation.But I turned 39 in indoc, and didn't have a job with much in the way of 401k benefits (2% match, 3 at best) until I got here.
