Your regulators have done a very good job in a very short time. You should all be thankful.

Themselves contend in vain. - Schiller
And as a special favour, here is a couple of photos I just took of a scrapped first stage blade. There are well over 100 cooling channels in it, most thinner than a small needle. Many of them are not circular either.
It's about twice/ three times life size.
Pace and Brooksg will now explain how each of those little holes on each blade or vane in every affected engine is going to be cleaned and checked for volcanic glass.
Leprechauns? Little elves perhaps? The best I can think of is an alkaline cleaner, but of course I don't know what that will do to any ceramic coatings or the metallurgy, including hydrogen embrittlement etc.
