Some very thoughtful responses.
I recall being a bit nervous many years ago, but had some experiences that reversed the psychology. - although I'm not suggesting it for anyone else.
I used to go to Nigeria a lot in the early 90's. Boy was it dodgy. I enjoyed various bouts of illness, near death by traffic, held up at gun-point with an AK-47 barrel pushed hard into my temple. The journey out to the airport was horrible and I felt very exposed. Even the airport offered no security, you ran the gamut of corrupt officials all the way up to the steps of the plane and there were stories of random 'arrests.' The only time I truly felt safe was when I got to the top of the steps and handed my boarding card to the FA. The first glass of champagne was the signifier that I could relax.
I spent many further years flying to Pakistan (survived a hotel bombing!), Central America and other places with a high degree of risk. As a result, in my mind the plane is the place of safety. I can drop my guard, nobody can bother me, I am back in my comfort zone.
