Banana peel
For a few posts it was good to see what the posters' area of expertise was. So, let me state at the start that I have none relating to the subjects on discussion.
Anyhow, having followed this thread for last two days and read most (if not all) post which did not concern themselves with media context, I cannot recall comments on couple of aspect of the damage.
If we were to fold back the three of so main pieces of fuselage skin, where would the centre of the break be? The way I see it - right along the lap joint. Look at the angles the lower and upper tears on the right diverge away from each other. The top part with two stringer chunks reaches down close to lap joint. I'd say, that oxy tank must have hit bullseye. I'd rather side with recent posts - "dislodged and out the hole" tank more plausible than a rocketing one.
Back to the broken skin. On the lower part blown outward, it looks to have an inward folded edge, which also looks to be curved. Or, is this just an illusion on a 2D photo?
Just curious.
