It is still surprises me even after many years of "Tin Bashing" just how much damage something of only a few pounds made of nothing more than blood, beak, bones and feathers can do to the metal structure of an aircraft.
Looks like loads of work there wiring looms, system pipelines, static stuff and that's before we even contemplate the tin bashing part of it, post repair pressure tests, functioning other stuff plenty to keep you busy there.
