Excellent post Trans World as well as others. I have watched many videos to understand how planes fly. I am a numbers person in both education and career experience and I know how statistically safe it is, I just am irrational. My concern is that there are so many freaking moving parts on these planes and so many chances for something to go wrong. I know they are built around redundancy but that’s just me being irrational again. Fires are a big worry. Not worried about all those buttons in cockpit but that is intimidating, not sure how you all keep up with that! Doesn’t help that last flight I took the pilot nailed the tail of the plane on the ground when taking off and having seen that tv show “air disasters” just months before where it described a southwest accident having been caused by a hairline fracture in the tail from a tail strike that happened many months before the accident.
