I'm guessing that even reports from the IAA or AAIB wouldn't persuade you.

Wrong. A respectably-published report would convince me. I'll
wait until someone points it out.
The pictures look like it had STD'd fiberglass wing extensions
or Flint tip tanks, and if so, that may be all that's missing, not part
of the actual wing structure. And not five feet. Whacking off wing
structure will often damage the wing root structure as well, causing
much more serious damage.
