Quote from Machinbird:
"Isn't there is a piece of the leading edge flap visible & retracted.
[...] look to the left of the large hole in the leading edge. The airfoil profile seems to be complete there."
I see what you are looking at, but I think we need a closer look to tell if it is merely the leading edge behind the slat, as gonebutnotforgotten suggests, or a small length of retracted slat.
