This NTSB photo looks aft over the top side of the left rear fuselage. It shows the left center and left aft vertical stabilizer attachment points.
Note the lower center portion of the picture. It shows a gaping hole thru the fuselage where the aircraft's torn skin is bent upwards and outwards. This area, as well as the area immediately downwind of the gaping hole, is colored by dark residue. Can this be evidence of an in-flight explosion from inside the fuselage, near the left side of the vertical stabilizer?
You mean like from a shoe-bomber, perhaps from inside one of the rear lavatories instead of foolishly trying to ignite them from his seat?
