It's a strange fuzz, but this explains a lot to an oldtimer that's used to metal.
and the cowls are carbon composite...
I wonder if the entire pod rotated/distorted jet pipe down just a tad as the front's impacted.
I was aware of the possibility of pod strikes before coming on this site. The BBC news had given some clue or another. For me it seems the best bet now the fuzzy surface might be explained.
