This is a 2 line summary of what I was trying to say above:
The USAF photo reduced to 2 levels of gray shows a narrower left wing cuff compared with that on the right wing.
IF the left wing cuff is actually narrower, then some of the left wing cuff may be missing.
That's all.
I have no other reason to suggest damage to the cuff.

Except, of course, that most (by a large margin) of the
debris hits are on the underside of the wing cuffs.
