A black hole in a dark material with a dark void within, against a

wheatfield.

Dark material? The RCC is light grey...

especially since they'd have been looking at tiles in the vicinity
anyway.

Yes - at the *tile*, that does not imply a close look at the *RCC*.

"Houston, Columbia... we just sent EV1 over the side and he says the
tiles look fine, but he wants to know if that big hole in the wing
leading edge he had to climb past is important..."

To be fair, I think Derek was referring to photography by "national
assets", not an EVA inspection.

Derek is possibly correct to say that remote photographic inspection would
not have revealed the hole. If NASA had asked for photos, they would have
optimized the sun angle for the tiles, and at non-optimal sun angles, the
RCC can indeed appear darker, so the contrast may not have enough to show
anything - "black on black", as Derek put it.

An EVA inspection would obviously have found the hole, since the EV would
have to look past the RCC in order to see the tiles.
