From the man who did inspection right after it happened. The fuselage was tilted in dolly. Horizontal stab pins were touching fin box. That is where lightening entered. There is no visible evidence of exit, anywhere. Suspected maybe went down the fin, jumped to trailer and forward out to ground through safety chain that was attached to tie down stake at front of trailer. Inside of fin was shattered and frayed only partially down from entry point..No visible damage to fuselage. Aircraft was totalled because of these unknowns.
