Fear of flying is at best irrational the way it pops it's head up now and then. Triggers personal to the person, based on something, based on nothing depending. I had it some years back for a year or so where I was flying as much as pilots do and whilst most flights were ok, there were a few episodes that were so awful, full on panic attacks and a trip in an ambulance from the air-stairs to hospital so bad was the feeling.
As to repeating a question, if you're anything like me you might forget something you typed in a while back, and there's been a bit going on in the world since 2019 for most people! Sometimes an old thread will be restarted and I realise that I had already made several posts in the thread, but completely forgotten about them.
