Just curious... Do the pictures show where the lightning struck the airplane, or are they showing where the lightning departed the airplane?
Most of the lightning strikes that I am familiar with (I date back to the pre-composite-aircraft-parts days) generally involved the lightning hitting at one point on the airframe and exiting at another point. I've know of wing-tips being blown off when lightning hit the nose radome, tailcones getting knocked off when lightning hits the wing-tips, etc.

Quoting Jerald01 (Reply 2): Just curious... Do the pictures show where the lightning struck the airplane, or are they showing where the lightning departed the airplane?
That is an exit wound.... entry wounds are normally pretty small and hard to find. Entry wounds normally look like a small spot weld. Anyway, I heard once that the actual lightening bolt is actually about the size of a human hair and nine times out of ten the entry is at the nose area or radome..exit on the tail, tip of the tail or in this case the horizontal. What happened here was the path out was the Horizontal Trim Tab rods. The lightening traveled down the rod until it got to the trim tab bearing rod end. That offered a greater resistance and stopped the path. When the energy built up.. it 'exploded' and blew off the rod ends and trim tab. Quite common actually.
